**Review 2-D Geometry Test**Read each question and answer carefully. Click on the screen to find the correct answer. Compare the correct answer to the answer you found.**Identify each polygon by its sides. Then classify the**polygon as convex or concave. Identify the figure as regular or non-regular. Octagon Concave Non-regular Hexagon Convex Regular**Identify the triangles by their angles and their sides**Scalene Right Acute Equilateral Isosceles Obtuse**Find the measure of each missing angle.**100 100 X 68 37 Y 80 X = 75 Y = 80**Find the area and perimeter of each shape.**A = 30 in² P = 30 in 5in 3m 4m 12in 7m A = 21 m² P = 22 m 11ft 2.5ft 8ft 7ft 10ft 21ft A= 112ft² P = 48ft A=25ft² P= 25 ft**Find the area and circumference of the figure.**D= 10m R=5m Area= m² C = = 10m**Word Problems**• One side of a square is 6 m long. How long is each of the other three sides? • The side of a square is 3 meters long. What is the area? • A label on a 1-gallon can of paint indicates you can cover about 400 square feet of surface. Is that enough paint to cover a rectangular wall that measures 25 feet by 8 feet? • The distance from the center of a circle to the edge of the circle is 2 feet. What is the greatest distance across the circle? 6meters 9 m² Yes. 8 x 25 = 200 4 ft since that is the diameter which is the greatest distance**Transformations: List all of the following types of**transformations that satisfy each description: reflection, translation, rotation. • a. The transformation is also called a turn. • b. The transformation preserves the orientation of a figure. • c. The transformation is the composite of successive reflections over two intersecting lines. • d. The transformation is the composite of successive reflections over two parallel lines. • e. A specific transformation is defined by a fixed point and a specified angle. • f. The transformation is also called a slide. • g. The transformation is also called a flip. rotation translation rotation translation rotation translation reflection**Determine the number of lines of symmetry for each figure**described below. Four • a. a square • b. an isosceles triangle (not equilateral) • c. a regular hexagon • d. an isosceles trapezoid • e. the letter E one Six one one**Transformation Impact**Sam has a rectangular garden plot 25 feet by 50 feet. He plans next year to cut down on the size of the garden. The new dimensions will be changed by a factor of 4/5. Which statement is true about the area of next year’s garden? The area of next year’s garden will be reduced by: • 4/5 • 16/25 • 8/25 • 64/125 B. 16/25**Pythagorean Theorem**• You place the base of a 10 foot ladder 8 feet from a building. How high does the ladder reach? • 6 ft • 12 ft • 20 ft • 36 ft A. 6ft**Pythagorean Theorem**Teddy is making a picture frame for his mother. The dimensions of the frame are 18 inches by 10 inches. What should the diagonal measure in order to have each corner be a right angle? • 18 in • 28 in • 20.591 in • 21.345 in C. 20.591 in
