### What are Congruent Angles - 7th Grade Math

Congruent Angles are the angles which are equal in measurement either you measure in degrees or radians.
The lines which create these angles can be any length.  Also they don’t have to point in same direction.
As long as the two angles are equal in measurement they are congruent Angles.

### What are Complementary Angles - 7th Grade Math

Let's say you have two angles, each one is 45 degree. If you add them up and the sum is 90 degree then those angles are Complementary angles.

Consider few more examples

70 degree and 20 degree
35 degree and 55 degree
10 degree and 80 degree

all above are Complementary angles as the sum of both is equal to 90 degree or right angle.

### Alternate Interior Angles - 7th Grade Math

Before we go for the definition of Alternate Interior Angles, let's define Transversal line.

Transversal line is a line that crosses at least two other lines. As we know the definition of Transversal line now. Let's consider we have two lines and they are crossed by a line ( Transversal line).

The angles on opposite side of transveral line and also inside of two lines which are crossed by Transveral line are called Alternate Interior Angles.

### Alternate Exterior Angles - 7th Grade Math

Before we go for the definition of Alternate Exterior Angles, let's define Transversal line.

Transversal line is a line that crosses at least two other lines. As we know the definition of Transversal line now. Let's consider we have two lines and they are crossed by a line ( Transversal line).

The angles on opposite side of transveral line and also outside of two lines which are crossed by Transveral line are called Alternate Exterior Angles.
