Geometric Interview Questions And Answers

Angles created when a transversal intersects with two lines. Alternate exterior angles lie on opposite sides of the transversal, and on the exterior of the space between the two lines.

A pair of angles created when a transversal intersects with two lines. Each angle in the pair is on the same side of the transversal, but one is in the exterior of the space created between the lines, and one lies on the interior, between the lines.

At a 90 degree angle. A geometric figure (line, segment, plane, etc.) is always perpendicular to another figure.

The common endpoint of two rays at which an angle is formed.

angles on the opposite sides of the transversal and on the interior of the parallel lines
The pair of angles in between the two lines cut by the transversal and on alternate sides of the transversal. Alternate interior angles are congruent if and only if the two lines crossed by the transversal are parallel.
Two angles that are on the inside of the parallel lines and opposite sides of the transversal. These types of angles are always congruent to one another.
The pair of angles in between the two lines cut by the transversal and on alternate sides of the transversal. Alternate interior angles are congruent if and only if the two lines crossed by the transversal are parallel.
The stylish pair of angles that are in between the two lines cut by the transversal and on alternate sides of the transversal. They're congruent if and only if the two lines crossed by the transversal are parallel.

A system that has perpendicular axes, usually the x- and y-axis.
The flat grid we use to plot out functions. It has an x-axis, a y-axis, and a very big name.
A grid made up of two perpendicular number lines.

chocolate or brownie fudge? ; a solid with circular base and a curved side that ends in one point and has one vertex; a duncecap
A three-dimensional solid with a circular base and one vertex. We prefer to think of it as the waffle thing that ice cream comes in.
A 3D solid with a circular base and a curved surface that meets at a point. Essentially, a pyramid with a circular base.
An object that tapers from a circular base to a point. Just like a birthday hat.

angles that share a terminal side
Angles that occupy the same position on the unit circle.
Angles that start and end at the same spots (usually start at θ = 0). They are different in the direction they travel or how many times they go around. (e.g. 270° and -90°, 30° and 360°).

A value that doesn't change, like pride in one's football team. Exception: the entire Philadelphia Eagles fan base.
A value that doesn't change. In a polynomial, the constant is the number that's not being multiplied by a variable, like the 4 in x2 + 11x + 4.
A value that does not change. Stay gold, Ponyconstant!
A number that doesn't change. Sometimes, we use this to mean a constant term, which is a number that isn't multiplied by any variables. In the expression 3y + 6, the 6 is a constant term, but the 3 can also be thought of as a constant.
A number that doesn't change. Disproves the whole, "The only constant is change," idea, doesn't it?
A number that doesn't change in value. Like ½ or -7 or 38,501.
A value that does not change because it's old-fashioned and thinks everything is fine as is. When we look at an expression like 6x + 2, the 2 is the constant.

A closed figure wherein points on the boundary are equidistant from the fixed center. More importantly, it's the shape of a pizza pie.
The set of all points in a plane that are exactly r units away from point O, where r is the radius and O is the center. The basis for such artifacts as wheels, wedding rings, and many types of cookies. We write "⊙O" to denote "the circle with center O."
A perfectly round two-dimensional shape. More technically, it's the set of all points that are the same distance away from another point (called the center).
A round conic defined by an eccentricity of 0. Also, a favorite shape for the terminally lost.

angles on opposite sides of the transversal and on the exterior of the parallel lines
The pair of angles on the outside of the two lines cut by the transversal and on alternate sides of the transversal. Alternate exterior angles are congruent if and only if the two lines crossed by the transversal are parallel.
Two angles that are on the outside of the parallel lines and opposite sides of the transversal. These types of angles are always congruent to one another.
The pair of angles on the outside of the two lines cut by the transversal and on alternate sides of the transversal. Alternate exterior angles are congruent if and only if the two lines crossed by the transversal are parallel.
The pair of angles on the outside of the two lines cut by the transversal and on alternate sides of the transversal. Alternate exterior angles are congruent if and only if the two lines crossed by the transversal are parallel. Also: as the name suggests, they're kind of hipster.

A portion of a line with a fixed endpoint on one end that extends without bound in the other direction.

A pair of angles whose measures sum to 90 degrees. Each angle in the pair is the other's complement.

An angle whose measure is less than 90 degrees.

reducing the numerator of one fraction with the denominator of another when multiplying fractions; wearing bright orange on top might cancel the orange pants your date has on

numbers in a pattern that are separated by a common difference

A zero degree angle. It is formed by two rays that share a vertex and point in the same direction.

A pair of angles whose measures sum to 180 degrees. Each angle in the pair is the other's supplement.

A 90 degree angle. It is the angle formed when perpendicular lines or segments intersect.

A line or segment that is perpendicular to a segment and contains the midpoint of that segment.

An angle whose measure is greater than 90 degrees.

A geometric figure consisting of the union of two rays that share a common endpoint.

Angles that share a vertex, one side, and no interior points.

A line that intersects with two other lines.

Lines that never intersect.
