Warm Up Solve for x. 1.16x – 3 = 12x + 13 2. 2x – 4 = 90 ABCD is a parallelogram. Find each measure. 3.CD4. mC
Rectangles A quadrilateral is a rectangle if: Opposite sides are congruent Opposite sides are parallel Opposite angles are congruent Consecutive angles are supplementary All four angles are right angles Diagonals are congruent Diagonals bisect each other Diagonals create 4 isosceles triangles.
1. If m ∠ 1 = 30, find m ∠ 2. 2. If m ∠ 6 = 57, find m ∠ 4. 3. If m ∠ 8 = 133, find m ∠ 2. 4. If m ∠ 5 = 16, find m ∠ 3.
Quadrilateral QUAD is a rectangle. Find the value of x. 1. DU = 26, QP = 2X + 7
3. m ∠ 4 = 6x – 16 m ∠ 2 = 2x + 4
4. DP = 4x + 1 QP = x + 13
5. m ∠ 3 = 70 – 4x m ∠ 6 = 18x - 8
