7-2 Review

Conditions are given. Will all triangles satisfying the same conditions be congruent? Use one of the four theorems to justify your answer.

1. In triangle JTP, m<T = 66°, m<P = 51°, TP = 3 cm Yes, SAS

2. In triangle HOG, m<H = 53°, m<O = 47°, and m<G = 80° No, AAA does not work

7 7 properties of parallelograms
7-7 Properties of Parallelograms
  • Opposite sides are congruent.
  • Opposite angles are congruent.
  • The diagonals intersect at their midpoints.
example
Example

In parallelogram WXYZ, WQ = 4, XQ = 6, and YZ = 7.

W X

Q

Z Y

Find QY and WX.

symmetry in parallelograms
Symmetry in Parallelograms
  • Every parallelogram has 2-fold rotation symmetry.
  • Parallelograms are not necessarily reflection-symmetric (unless they are a rectangle, rhombus, or square).
example1
Example
  • Find x and y. 6x + 9

R Y

4 2y

N A

2 – x

2 - x = 6x + 9

2 = 7x + 9 4 = 2y

-7 = 7x 2 = y

-1 = x
