Question

1. Which of the following statements are false? (2 points)

Vertical angles are congruent.
Angles with measures between 0 and 90° are complementary.
Straight angles are supplementary.
Angles with measures between 90° and 180° are obtuse.

Answer 1

Answer:angles with measures between 0 and 90 aren't always complementary

Explanation:

complementary angles have to have a sum of 90 degrees, but just because 2 angles have measures between 0 and 90 degrees does not make them complementary. For example 46+44=90 degrees and those numbers are both between 0 and 90, but 89+2 doesn't equal 90 but the numbers are both between 0 and 90.

Answer 2

Angles with measures between 0 and 90° are complementary.

Explanation:

Vertical angles are congruent.

Vertical angles are same . so they are congruent. So its true

Angles with measures between 0 and 90° are complementary.

when the sum of two angles is equal to 90 degree then they are complementary. So this statement is false

Straight angles are supplementary.

Angles in a straight line is 180 degree. So its true.

Angles with measures between 90° and 180° are obtuse.

The angle above 90 degree is obtuse. So its true
