Day 3 - #24-34 Fall Geometry Final Exam Review

Front

What are complementary angles?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

If m∠PQR = 38°, what is m∠RQS if they are complementary?

Back

m∠RQS = 52° (since 90° - 38° = 52°).

Front

What is the Substitution Property of Equality?

Back

If a = b, then a can be replaced by b in any expression.

Front

What are the properties of angles formed when two parallel lines are cut by a transversal?

Back

Corresponding angles are congruent, alternate interior angles are congruent, and consecutive interior angles are supplementary.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal parts.

Front

What is the difference between supplementary and complementary angles?

Back

Supplementary angles sum to 180 degrees, while complementary angles sum to 90 degrees.

Front

If m∠3 = 7x - 13 and m∠6 = 2x + 37, how do you find m∠4?

Back

Set up an equation based on the relationship between the angles, solve for x, then substitute back to find m∠4.

Front

What type of triangle has one angle greater than 90 degrees?

Back

An obtuse triangle.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and between the two lines.

Front

How do you classify a triangle based on its angles?

Back

Triangles can be classified as acute (all angles < 90°), right (one angle = 90°), or obtuse (one angle > 90°).
