This is the one of the geometric shapes that literally makes the construction of perfectly straight edges possible. Using the Pythagorean theorem, we can find missing sides of these shapes. As we advance into trigonometry, we will learn that you do not much information at all about these shapes to be able to determine all of the angles and lengths of sides. Something that people often do not realize is that if put a diagonal line across a rectangle and cut along that line, you have just created two right-angled triangles. Contractors use the property of geometry all day to create perfectly level and straight structures. This series of lessons and worksheets teach students how to complete figure out all measures on right triangles through a wide variety of techniques.

Here are the instructions how to enable JavaScript in your web browser. On this webpage you will find our range of worksheets to help your child to work out the area of a range of right triangles and triangles with their perpendicular height given. The reason that you simply need to multiply the two perpendicular sides together and halve the answer to find the area of a right triangle is quite straightforward to understand. If you look at the triangle above, you will notice that the red dotted line that joins the triangle forms a rectangle. The area of the right triangle is exactly half of this rectangle because it has been split into two identical congruent right triangles with the same area. However, we can also see that the area of the rectangle has to be b x h because to find the area of a rectangle, you multiply adjacent sides together. In Sheets 1 and 2, the perpendicular heights are all given - so they are straightforward to solve. Sheet 3 is much trickier as Pythagoras' theorem is needed to find the missing perpendicular height before the area can be worked out. These sheets contain a mixture of right triangles and triangles where the perpendicular height is given. The focus on these sheets is angles on a straight line, angles around a point and angles in a triangle. This will take you to a new webpage where your results will be shown. You can print a copy of your results from this page, either as a pdf or as a paper copy. For incorrect responses, we have added some helpful learning points to explain which answer was correct and why.

The angles are often labeled which allows you to name the triangles. If the shape is measured in cm, then the area would be measured in square cm or cm 2 If the shape is measured in inches, then the area would be measured in square inches or in 2 How To Find the Area of a Right Triangle To find the area of a any triangle, you simply need to multiply the base of the triangle by the perpendicular height and halve the answer.
