Lesson 9 Unit 2: Geometry Unit Test Part 1

Question 1:
*There is an image*
Name a pair of complementary angles.
A.) ∠1 and ∠4
B.) ∠1 and ∠6
C.) ∠3 and ∠4
D.) ∠4 and ∠5

Answer 1

Please help Ms. Sue

Answer 2

No one can help you unless you explain the image but I will give you the definition of a complementary angle

A complementary angle is two angles that add up to 80 degrees
Here is something I came up with to help you remember
“The angles are completing each other for being right.”
Hope this helps

Answer 3

I don't know how to

Answer 4

To anyone who knows the image I speak of please help

Answer 5

Add up two angles measurements if the measurement equal 90 degrees it is a complementary angle

Answer 6

Thank you, Anna, that a little more helpful.

Answer 7

if m ∠ 1 = 50 , what is m ∠ 5

1. 50
2. 40
3.35
4.25

Answer 8

The correct answer is 40. This is because ∠1 and ∠5 are vertical angles and therefore have the same measure. Since ∠1 has a measure of 50, ∠5 must also have a measure of 50.
