Understanding different types of angles and that angles in a triangle sum to 180° can be helpful when classifying a triangle. Recognising line symmetry and rotational symmetry will also help. Look for ...
The basic formula for calculating the area of a rectangle in Excel is length * height. Thus, the syntax of the formula for finding the area of a rectangle in Excel would become: Eg. Let us assume we ...
\(a^2 + b^2 = c^2\) calculates the length of the longest side. To calculate the length of one of the shorter sides, rearrange the formula to make \(a^2\) or \(b^2\) the subject. \(a^2 = c^2 - b^2\) or ...
