### Congruent Angles

When two angles have the same measure, we say that they are **congruent**. Congruent means having the same size and shape. When we look at angles, remember that we are only concerned with how wide the opening is. We may draw the rays longer or shorter, but the angles are still congruent.

Angles RST and XYZ are congruent because they have the same measure. We use the symbol

"" to show that two figures are congruent.

is read "Angle RST is congruent to Angle XYZ."
