Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

Define Alternate Interior Angles.

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method to prove triangles are congruent by showing two angles and a non-included side are equal.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles are equal, each measuring 60 degrees.

Front

What is the definition of an acute triangle?

Back

An acute triangle is a triangle where all three interior angles are less than 90 degrees.

Front

What is the difference between scalene and isosceles triangles?

Back

A scalene triangle has all sides of different lengths, while an isosceles triangle has at least two sides of equal length.

Front

What is the formula for finding the exterior angle of a triangle?

Back

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Front

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two lines. They are supplementary when the lines are parallel.
