Choose a 'study mode'

Notes

Definition: a quadrilateral with two pairs of parallel sides

Types of Parallelograms:

Rhombus - a parallelogram with four congruent sides
Rectangle - a parallelogram with four right angles
Square - a parallelogram with four congruent sides and four right angles

Properties of Parallelograms:

Opposite sides are parallel
Opposite sides are congruent
Consecutive angles are supplementary
Opposite angles are congruent
The diagonals bisect each other

7.2 - Rectangles, Squares, & Rhombii

Learn:

Notes:

A rectangle is a parallelogram with 4 right angles and congruent diagonals
A rhombus is a parallelogram with 4 congruent sides. The diagonals of a rhombus are perpendicular bisectors.
A square is a parallelogram, a rectangle, and a rhombus. It follows all of the rules of these three shapes combined.

Use the diagram below for your notes

7.3 - Trapezoids

Learn:

NOTES

The parallel sides are called bases
The other sides are called legs
Angles on the same leg are supplementary

Isosceles Trapezoids:

Congruent legs
2 pairs of congruent base angles
Congruent diagonals

7.4 - Kites

Learn:

Notes

Kites have two pairs of adjacent congruent sides, and the diagonals are perpendicular.
The diagonal through the vertex angles bisects the vertex angle and the other diagonal.
The non-vertex angles are congruent.

Unit 7 Project Rubric

7.5 - Distance & Slope

Learn:

Notes

Congruent segments have the same length. We can use the distance formula to find the length of a segment.

Parallel segments have the same slope. We can use the slope-intercept formula to find the slope of a segment.

Perpendicular segments have the opposite inverse slope. We can use the slope-intercept formula to find the slope of a segment.
