Right triangle: - 90 degrees
- Has 3 sides
- Has a hypoteneuse
Square: - Has 4 sides
- All equal in length
- The angles are 90 degrees.
Legs: The shorter part of the right angle triangle.
Hypotenuse: The longer part of the right angle triangle.
R.A.T: The abbreviation of Right Angle Triangle, which is a triangle that has a right angle in the corner
Greek: A nation and ethnic group native to Greece.
Theorem: A theoretical statement representing something to be proved from other formulas.
Pythagoras' theory was called The Pythagorean Theorem. It stated that the sum of two squares (square a and b) equals a bigger square (square c). Those squares are related to the Pythagorean theorem. The equation for the theorem is a² + b² = c².
Pythagoras is important to us in grade 8 math because he created this formula.
c² - b² = a²
10² - 8² = a²
10x10 - 8x8 = a²
100 - 64 = a²
36 = a²
√¯36 = a
6 = a
a² + b² = c²Square = 225 cm²
√¯225 = a
a = 15
The triangle's length and width is 15 cm².
a² + b² = c²
24² + 24²= c²
576 + 576 = c²
1152 = c²
√¯1152 = c
33.941 = c
