Studdy Solution

STEP 1

What is this asking? Which angles have the same measurement as angle 2, which is 5050^\circ? Watch out! Don't mix up corresponding and vertical angles!

STEP 2

1. Find the vertical angle
2. Find the corresponding angle
3. Find the other vertical angle

STEP 3

We're given that angle 2 is 5050^\circ.
We're looking for **congruent angles**, which means angles with the *same measurement*.
Let's start by looking for a **vertical angle**.
Vertical angles are formed by intersecting lines and are *opposite* each other.

STEP 4

Angle 4 is the vertical angle to angle 2.
Vertical angles are **always congruent**.
So, angle 4 is also 5050^\circ!

STEP 5

Now, let's think about **corresponding angles**.
These are angles that are in the *same position* when a line crosses two parallel lines.
Since the lines are parallel, corresponding angles are **congruent**.

STEP 6

Angle 2 and angle 6 are corresponding angles.
Since angle 2 is 5050^\circ, angle 6 must also be 5050^\circ!

STEP 7

We found that angle 6 is 5050^\circ.
Let's find its vertical angle.

STEP 8

Angle 8 is vertical to angle 6.
Since vertical angles are congruent, angle 8 must also be 5050^\circ!

STEP 9

Angles 4, 6, and 8 are congruent to angle 2.
So our answer is 4, 6, 8.
