Quadrilaterals and Their Parts

In this topic, we learn to identify quadrilaterals and their parts. This track covers the identification of quadrilaterals based on the length of sides and measure of angles.

Topic: Understand Quadrilaterals and their Parts

  • A quadrilateral is a polygon that has 4 sides. Another name for a quadrilateral is quadrangle. All quadrilaterals have 4 sides, 4 vertices, and 4 angles

  • The sides are the lines segments that form the quadrilateral

  • The vertex is the point where two sides meet; an angle is formed by two sides that meet at a vertex

  • Quadrilaterals have 4-letter names. You name a quadrilateral by listing the letters for each vertex in order

  • A diagonal connects one vertex to another vertex. The vertices should not be adjacent. A quadrilateral has 2 diagonals

Topic: Classify Quadrilaterals

  • A quadrilateral is a polygon that has 4 sides. Another name for a quadrilateral is quadrangle. All quadrilaterals have 4 sides, 4 vertices, and 4 angles

  • Quadrilaterals are classified according to the length of their sides and the measure of their angles; a quadrilateral with 4 right angles and 4 equal sides is a square

  • A quadrilateral with 2 pairs of parallel sides is a parallelogram; a quadrilateral with 4 equal sides and no right angles is a rhombus

  • A quadrilateral with exactly 1 pair of parallel sides is a trapezoid; a quadrilateral with 2 pairs of equal sides is a kite
