How do you find the missing angle in a triangle?

Back

To find the missing angle in a triangle, use the fact that the sum of all angles in a triangle is 180 degrees. Subtract the sum of the known angles from 180.

How do you write the equation of a line given two points?

Back

To write the equation of a line given two points, first find the slope (m) using m = (y2 - y1) / (x2 - x1), then use the point-slope form y - y1 = m(x - x1) to find the equation.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
