What do you mean by projection rule?

0 0

Ankit replied | 09/12/2016

Projection Formula gives the relation between angles and sides of a triangle. We can find the length of a side of the triangle if other two sides and corresponding angles are given using projection formula. If a, b and c be the length of sides of a triangle and A, B and C are angles opposite to the sides respectively, then projection formula is given below:
a = b cos C + c cos...  more»

What is the formula for measuring height of a triangle?

0 0

Ankit replied | 09/12/2016

The height of a triangle can be found if you have an angles and a side, if the angle is between the base and the side you have, or all three sides. We'll call the sides of the triangle a, b, and c, and the angles, A, B, and C.
If you have all three sides, you'll use Heron's formula, and the formula for the area of a triangle.
If you have two sides and an angle, you'll use...  more»

What is the difference between acute angle and obtuse angle of a triangle?

0 0

Ankit replied | 22/11/2016

An acute triangle is a triangle with all three angles acute (less than 90°). An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle.
