5.3 & 5.4

Front

What is the sum of the angles in a triangle?

Back

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

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any geometric figure is congruent to itself, e.g., MP ≌ MP.

Front

What is the Symmetric Property in geometry?

Back

The Symmetric Property states that if one figure is congruent to another, then the second figure is congruent to the first, e.g., if MP ≌ LM, then LM ≌ MP.

Front

If one angle of a triangle is 34 degrees and another is 101 degrees, how do you find the third angle?

Back

Subtract the sum of the known angles from 180 degrees: 180 - (34 + 101) = 45 degrees.

Front

What is the value of x if 2x + 4 = 36?

Back

x = 16.

Front

What does it mean for two segments to be congruent?

Back

Two segments are congruent if they have the same length.

Front

What is the definition of an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

Front

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

Back

The measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.

Front

If MP ≌ PM, what property is being used?

Back

The Reflexive Property.

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.
