Solving for sides/angles in Triangles

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects. They are equal when the lines are parallel.

Front

What is the distance formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

Front

Calculate the distance between the points (4, 3) and (0, 6).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If one angle of a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

What is the measure of angle b if angle a is 36 degrees and they are complementary?

Back

Angle b is 54 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

Find the measure of the indicated angle if angle x is 34 degrees and they are supplementary.

Back

Angle y is 146 degrees.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.
