Pure Maths A Level Questions and Answers 100% Pass Gradient y2-y1/x2-x1 Length of a line sqrt((x2-x1)^2+(y2-y1)^2) Midpoint (x1+x2/2, y1+y2/2) How do you know if two lines are perpendicular? When you multiply the gradients together they should equal -1. The general rule is perpendicular = -1/m. Or you could use Pythagoras to show there is a right angle How do you know if two lines are parallel? The gradients should be the same What should you always remember when finding the square roots?

A chart that tells you where the points of concurrency lie and what lines its made of based on the point and the type of triangle.

A chart that describes where the different points of concurrency lie and what they are made of . It is sorted by the type of point and the type of triangle.

The solution of triangle formula sheet is a set of formulas and equations used to solve various problems related to triangles. These formulas help in finding the measurements of angles, sides, area, perimeter, and other important properties of a triangle. Some of the common formulas include the Pythagorean theorem, which relates to the sides of a right-angled triangle, and the law of sines and law of cosines, which can be used to find the length of sides and angles in any type of triangle.
