Activity 2: Addresses achievement indicators 1 and 2 (loosely), and “prepares the garden”. Provide 1 cm grid paper. Ask students to draw a right triangle having side lengths of 3 and 4.A 3-4-5 right triangle is a triangle whose side lengths are in the ratio of 3:4:5. In other words, a 3-4-5 triangle has the ratio of the sides in whole numbers called Pythagorean Triples. This ratio can be given as: Side 1: Side 2: Hypotenuse = 3n: 4n: 5n = 3: 4: 5. We can prove this by using the Pythagorean Theorem as follows: ⇒ a 2 + b 2 = c 2.6.1 The theorem The Pythagorean theorem deals with right triangles. To repeat a few things we mentioned in Chapter 5: Right triangles are ones that have a 90 angle (which is called a “right angle”). A 90 angle is simply what you have at the corner of a rectangle. The two sides that meet at the right angle are perpendicular to each other.
