I need to know about congruent angles IN vertical angles for a test tomorrow.
The opposite ones are congruent. Show it with a couple of crossed sticks.

Thanks damon
Congruent angles are angles that have the same measure or size. Vertical angles are formed by the intersection of two lines. When two lines intersect, they form four angles, with two pairs of opposite angles. The important thing to know about vertical angles is that they are always congruent. This means that the measure of one angle is equal to the measure of its opposite vertical angle.
To identify and understand congruent angles in vertical angles, here are the steps you can follow:
1. Draw two intersecting lines, creating an X-shape.
2. Notice that the lines intersect at a single point, forming four angles.
3. Identify pairs of vertical angles, which are opposite each other.
4. Use a protractor or angle ruler to measure the angles.
5. Compare the measures of the angles in each pair of vertical angles.
6. If the measures of the angles are equal, then they are congruent.
7. Remember that congruent angles have the same size and can be denoted by the symbol ≅.
By following these steps, you can identify and determine congruent angles in vertical angles. Remember to review these concepts before your test to ensure a better understanding.
