5.4 Properties of Midsegments

5.4 Properties of Midsegments powerpoint

5.4 Properties of Midsegments pdf

 

In this lesson you will

 

● Discover properties of the midsegment of a triangle

● Discover properties of the midsegment of a trapezoid

 

 

 

In Chapter 3, you learned that a midsegment of a triangle is a segment connecting the midpoints of two sides.

In this lesson you will investigate properties of midsegments.

5.3 Kites and Trapezoids

5.3 Kites and Trapezoids powerpoint

5.3 Kites and Trapezoids pdf

 

In this lesson you will

 

● Investigate the properties of kites

● Investigate properties of trapezoids and isosceles trapezoids

kite is a quadrilateral with two distinct pairs of congruent consecutive sides.

The angles between congruent sides are called vertex angles. We’ll refer to the other two angles as nonvertex angles.

A kite has one line of reflectional symmetry, just like an isosceles triangle.

 

A trapezoid is a quadrilateral with exactly one pair of parallel sides.

The parallel sides are called bases.

A pair of angles that share a base as a common side are called base angles.

5.2 Exterior Angle Sum

5.2 Exterior Angle Sum powerpoint

5.2 Exterior Angle Sum pdf

 

In this lesson you will

 

● Find the sum of the measures of one set of exterior angles of a polygon

● Derive two formulas for the measure of each angle of an equiangular polygon

In Lesson 5.1, you discovered a formula for the sum of the measures of

the interior angles of any polygon.

In this lesson, you will find a formula for the sum of the measures of a set of exterior angles.

 

 

To create a set of exterior angles of a polygon, extend each side of the polygon to form one exterior angle at each vertex.
