Pairs will check in with me when they can explain the height of a slope triangle with a base 1. I can identify if two triangles are similar. The slope of a line can sometimes be positive or negative.
Show that the given vertices form a right angled triangle and check whether its satisfies pythagoras theorem.
The resulting value will be the height of your triangle. 20 2h Multiply 4 by 12. When a line has a negative slope the ratio of the side lengths of the triangles formed remains positive and is equal to the absolute value of the slope. Imagine that you are flying a plane and have ascended vertically 1000 feet.
