Angle abc is rotated 90 degrees counterclockwise about the origin to form angle a’b’c’. which statement shows the measure of angle a’b’c’? m∠a’b’c’ = 90 degrees m∠a’b’c’ = 180 degrees m∠a’b’c’ = m∠abc m∠a’b’c’ = 2 × m∠abc

m∠A’B’C’ = m∠ABC

Step-by-step explanation:

Given : Angle ABC is rotated 90 degrees counterclockwise about the origin to form angle A’B’C’.  

To Find: Which statement shows the measure of angle A’B’C’?

Solution:

We are given that Angle ABC is rotated 90 degrees counterclockwise about the origin to form angle A’B’C’.  

Rotation takes place here.

Rotation does not changes the measure of angle  

So, the measure of angle will remain same  

m∠A’B’C’ = m∠ABC

So, Option C is true .

Hence The statement shows the measure of angle A’B’C is m∠A’B’C’ = m∠ABC

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
