Unit 2.3 Make Up Assginemnt

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of all angles in a triangle is 180°.

Front

Find the measure of angle x if the other two angles are 70° and 60°.

Back

x = 50° (because 70° + 60° + x = 180°)

Front

What is the measure of a right angle?

Back

A right angle measures 90°.

Front

If one angle of a triangle is 90° and another is 45°, what is the measure of the third angle?

Back

The third angle measures 45° (because 90° + 45° + x = 180°).

Front

What is the measure of a straight angle?

Back

A straight angle measures 180°.

Front

Find the indicated angle if one angle is 37° and the other is 143°.

Back

The indicated angle is 0° (because 37° + 143° + x = 180°).

Front

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

Back

The sum of the interior angles of a quadrilateral is 360°.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of complementary angles is 90°.

Front

If two angles are supplementary, what is the sum of their measures?

Back

The sum of supplementary angles is 180°.

Front

Find the measure of an angle if its supplement is 120°.

Back

The angle measures 60° (because x + 120° = 180°).
