Quadrilaterals Flashcard

Front

What is a quadrilateral?

Back

A quadrilateral is a polygon with four sides, four vertices, and four angles.

Front

What are the properties of a square?

Back

A square has four equal sides, four right angles, and its diagonals bisect each other at right angles.

Front

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

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

Define an isosceles trapezoid.

Back

An isosceles trapezoid is a trapezoid in which the non-parallel sides are equal in length.

Front

If one angle of a trapezoid is 112 degrees, what can you say about the other angles?

Back

The angles adjacent to the base of the trapezoid are supplementary to the angles at the other base.

Front

What is a median in a triangle?

Back

A median is a line segment joining a vertex of the triangle to the midpoint of the opposite side.

Front

How many medians does a triangle have?

Back

A triangle has three medians.

Front

What is the centroid of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect.

Front

What is the relationship between the angles in an isosceles triangle?

Back

In an isosceles triangle, the angles opposite the equal sides are equal.
