What is the definition of supplementary angles?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is the definition of similar triangles?

Back

Two triangles are similar if their corresponding angles are equal and the ratios of their corresponding sides are proportional.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are equal in measure.

Front

What is the relationship between corresponding angles in similar triangles?

Back

Corresponding angles in similar triangles are equal.

Front

What is the formula for finding the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon with n sides is given by the formula: (n-2) * 180 degrees.

Front

If angle A is 62 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle is 180 - 62 = 118 degrees.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines.

Front

If triangle PQR is similar to triangle STU, what can be said about the sides PQ and ST?

Back

The sides PQ and ST are proportional.

Front

What is the value of x if 2x + 10 = 30?

Back

x = 10.

Front

What is the definition of corresponding sides in similar triangles?

Back

Corresponding sides are the sides that are in the same relative position in two similar figures.
