Wayground #20: Similar Triangles/Slope

Multiple Choice

1. Which of the following statements best describes: Similar Triangles on a line?

• They have equal sides but unequal shapes.

• They share the same angle measures and side ratios are equal.

• They are always congruent.

• They have different side ratios.

Multiple Choice

2. WHY SLOPE IS THE SAME EVERYWHERE-

How do you make a right triangle?:

• Using Horizontal and Vertical Lines.

• Subtracting x and y.

• You have to only use Vertical Lines.

• Slope formula y = mx + b.

Multiple Choice

3. The formula for Slope is?:

• m = y+b

• m = (y2 - y1) / (x2 - x1)

• m = x2 - x1

• m = (y2 - x) + (y1 - x)
