Half the base times the height A triangle is a figure that is enclosed by three connecting segments. A right triangle has one angle equal to 90 degrees. The area is 1/2 the base times the height.

The answer depends on what information you have about the triangle - other than it is right angled.
There is no right triangle on the right! (Ignore the length of the hypotenuse of a right triangle.) if you have the length of the two legs (base and the upright side): (base x upright) ÷ 2 = area of the right angle triangle.
A right triangle is easy, simply multiply the two sides and divide by two. A non-right triangle is a bit more of a challenge. You have to make it a right triangle by adding a right triangle to it. Calculate and then subtract the area of what you had to add.
A right triangle with a hypotenuse of 10m and a base of 5m has an area of: 21.65m2
The area
it is 24in The area of the first triangle is 24 [(6*8)/2]. The area of the smaller triangle is 12 [24/2]. The two legs will have a relationship of [4/3x to x], the same as any right triangle.
