Warm-Up Sit in the same area where you sat before. Study for your quiz. What is the area of a triangle with a height of 4 inches and a base that is the length of 3 inches?

Clear Your Desk Except paper and pencil.

Finished with Quiz? Staple any work you have to your quiz and put your quiz in the class bin. Get your homework for tonight (the side with #4- 9 on it) from the front desk and write your homework in your Bull Book. Take notes on what you read. Open your textbook to page 397 and read to page 398. Look at #19 to know what a diagonal is. Read Lesson 9-3 and 9-4. What does congruent mean?

Area of Special Quadrilaterals Use your basic shapes that you know… triangles and rectangles to find the area. Two sides that have the same measurement are marked with a short line through the sides. Diagonal – a line that goes from one point on a shape through the middle to another point, not the edge though Hypotenuse – longest side of a right triangle, side of triangle that slopes Find area of a triangle using the base and height, not the hypotenuse

Homework Complete the back of your homework #1-6 due Friday. Fold your paper in half. On the top half, draw a special quadrilateral (one that we have discussed this week) and label the lengths of the sides and height. On the bottom half, put your answer and the work you did to solve your problem. Quiz on area of special quadrilaterals next Wednesday. Review Benchmark Test next Monday and Tuesday.

Warm-Up A rectangle measures 3 inches by 4 inches. If the lengths of each side double, what is the effect on the area?

Practice A rectangle measures 3 inches by 4 inches. If the lengths of each side double, what is the effect on the area? The lengths of the sides of a bulletin board are 4 feet by 3 feet. How many index cards measuring 4 inches by 6 inches would be needed to cover the board?
