Question

Find the measure of angle one and angle two if angle 3 =78° and angle 4=102°

Answer 1

Given the diagram

Given that <3 =78 degrees and

<4 = 102 degrees.

To get angle 1 (<1):

< 1 and <4 are corresponding angles

When two lines are crossed by another line (called the Transversal), the angles in matching corners are called Corresponding Angles.

Therefore: <1 = <4 = 102 degrees

`<1=102^0`

To get angle 2 (<2)

<2 and <3 are also corresponding angles

therefore

<2 = <3 =78 degrees

This means that

`<2=78^0`
