Front

What is the measure of ∠1 if it is given that ∠1 = 95°?

Back

∠1 = 95°

Front

Define Vertical Angles.

Back

Vertical Angles are two non-adjacent angles that are formed by two intersecting lines.

Front

Can segments of lengths 25 yd, 12 yd, and 37 yd form a triangle?

Back

No, because 25 + 12 is not greater than 37 (violates triangle inequality).

Front

What are Complementary Angles?

Back

Complementary Angles are two angles whose measures add up to 90°.

Front

What is m∠a if it is part of a linear pair with 48°?

Back

m∠a = 132°, linear pair.

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

What are Alternate Interior Angles?

Back

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

Front

What is the definition of Corresponding Angles?

Back

Corresponding Angles are angles that are in the same position on two parallel lines in relation to a transversal.

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°.

Front

What is a Linear Pair of Angles?

Back

A Linear Pair of Angles consists of two adjacent angles whose non-common sides form a straight line.
