Geometry 1st Semester Review

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 parallel lines. They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about corresponding angles?

Back

Corresponding angles are equal in measure when two parallel lines are cut by a transversal.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

How do you find the perimeter of a triangle?

Back

The perimeter of a triangle is found by adding the lengths of all three sides.

Front

What is the incenter of a triangle?

Back

The incenter of a triangle is the point where the angle bisectors of the triangle intersect, and it is also the center of the circle inscribed within the triangle.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is the relationship between the sides of a triangle and its midpoints?

Back

The segment connecting the midpoints of two sides of a triangle is parallel to the third side and half its length.

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more other lines at distinct points.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is the significance of the angle bisector in a triangle?

Back

The angle bisector of a triangle divides the angle into two equal parts and intersects the opposite side at a point that is proportional to the lengths of the other two sides.
