This document discusses geometric shapes like prisms and their properties. It aims to teach students to identify characteristics of shapes based on coordinates and reasoning, identify shapes after rotation, and calculate properties of prisms like their diagonals, bases, and base areas using formulas. Students are assigned homework on finding various measurements and properties of prisms.

2. LESSON OBJECTIVES
At the end of today’s lesson you will be able to:
– Identify the characteristics of different geometric shapes in terms of
coordinates method and logical reasoning.
– Identify the shapes after rotation.

3. What is a prism?

4. We have open forms of prism
Name each type of prism.

5. Diagonal of cube

6. 𝐷 = 𝑎2 + 𝑏2 + 𝑐2
Diagonal of cuboid(parallepipid, right
rectangular prism)

7. In right rectangular prism(cuboid)
measurement is 3x4x12 . Find base AC
and diagonal of the prism.

8. In the cuboid, the lateral edge is
5 cm, base edges are 6 and 8 cm,
one of diagonals is 12 cm. Find
diagonal of the base of the
cuboid.

9. Find base area of the prism

10. Find base area of the prism

11. Find base area of the prism
