triangle height formula

In a triangle when we refer to an angle, we mean the angle bounded by the two sides. The three angles lie in the interior region of the triangle. These angles are called the interior angles of the triangle. Now observe the triangle in which the sides are pr..

Concurrency of the angle bisectors of a triangle - Draw a triangle ABC. Draw its angle bisectors. The angle bisectors pass through a point. Recall the procedure to draw angle bisectors: With B as centre and with a convenient radius draw an arc of a circle to cut AB and AC at X a..

Solution of Right Angled Triangles - To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. In the figure, AB = 100 cm, find (i) x and (ii) y...

The area of a parallelogram is half of the area of the triangle. What is the height of the triangle, if they have the same base length of 6 cm and the area of the parallelogram is 39 cm 2 ? => 26 cm or 21 cm or 31 cm or None of the above..

Paul used a rubber band in a geoboard to make a triangle of area 72 cm 2 . What happens to the area of the triangle, if he doubles the base and keeps the height constant? => The area is doubled. or The area increases 4 times. or The area does not change. or The area in..

Find the base of a triangle, if area of the triangle A and height h are known. => h 2 A or 2 h A or 2 A h or 2A h..

An object seen through a telescope is in the form of a right triangle. If the actual height and base of the object is 28 cm and 39 cm and the height was 3 cm through the telescope, then find the length of the base of the triangle. => 8.34 cm or 4.17 cm or 4.6..

What is the area of a triangle with a height of 2 y - 5 and base equal to 2 times the height of the triangle? => 4 y 2 - 20 y + 5 or 4 y 2 - 20 y + 25 or 4 y 2 - 10 y + 25 or 4 y 2 - 10 y + 5..

Find the area of a triangle whose base is 20 cm and height is 5 cm. => 50 sq.cm or 40 sq.cm or 28 sq.cm or 25 sq.cm..

Summary - The height 'h' of a triangle ABC with base BC = 'a' is given by the formula: when the altitude falls within the base and when the altitude falls outside the base..
