**Construction Construct triangles with given conditions.**

Construct a ∆ ABC in which BC= 6cm, CA = 5cm, and AB = 4cm Construct a ∆ PQR in which PQ = 5.8cm, QR = 6.5cm and PR = 4.5cm Construct a ∆ LMN in which LM = LN=5.5cm, and MN = 7cm Construct a ∆ STU in which T=60° U = 70° and TU = 7.5cm Construct a right triangle ABC in which C= 90 °and B = 45, CB = 5cm Construct an equilateral triangle in which AB=BC=CA=6cm. Measure each angle.

**Easy as Pi It’s as Easy as Pi**

1. Carefully wrap string around the circumference of your circular object. 2. Cut the string when it is exactly the same length as the circumference. 3. Now take your “string circumference” and pull it across the diameter of your circular object. Cut as many “string diameters” from your “string circumference” as you can. 4. Repeat steps 1-3 with at least 3 different circular objects. 5. Record your results in the table. Use a calculator to find the ratio of circumference and diameter. What do you notice?

What’s My Solid Each of the following descriptions fit one or more solids (prism, pyramid, cone, cube, a cylinder). For each clue, describe what solid it may be and your justification for selecting that solid. If the description fits more than one solid, name and provide justification for each solid. Sketch the solid, and illustrate the properties described.
