Pythagoras
Slides in this set (2)
-
- Hypotenuse = line opposite the right angle
- Use the formula:
- C² = B² + A²
- Example:
- C² = B² + A²
- C² = 6² + 8²
- C² = 36 + 64
- C² = 100
- *Square Root It
- C = 10

Circumference, Diameter and Radius
- Circumference = Diameter x π (C = π d)
- Example 1:
- C= D π
- C= 4 x π
- C= 12,6
- Diameter = Circumference ÷ π (D= C ÷ π)
- Or Radius x 2 (D= R x 2)
- Example 2:
- D= 12,5 ÷ π
- D= 4
- Radius = Diameter ÷ 2
- Caption: 1. D- 4cm R- 2cm 2. C- 12.5
