How do you find the height of an equilateral triangle if you have the length of the hypotenuse?
An equilateral triangle hasn't a hypotenuse; hypotenuse means the side opposite the right angle in a right triangle. An equilateral triangle has no right angles; rather all three of its angles measure 60 degrees. Knowing the length of the hypotenuse of a right triangle does not give enough information to determine the triangle's height. But the length of a side (which is the same for every side) of an equilateral triangle is enough information from which to calculate the height of that triangle. The first way is simply to use the formula that has been developed for this purpose: height = (length X sqrt(3)) / 2. But you can also use the geometry of right triangles to solve for the height. That is because you can bisect the triangle with a vertical line from the top vertex to the center of the base. The length of that line, which splits the equilateral triangle into two right triangles, is the height of the equilateral triangle. We know a lot about each right triangle formed by bisecting the equilateral triangle: * - The hypotenuse length is the length of the equilateral triangle's side. * - The base length is half the length of the hypotenuse. * - The angle opposite the hypotenuse is 90 degrees. * - The angle opposite the vertical is 60 degrees (the measure of every angle of any equilateral triangle). * - The angle opposite the base is 30 degrees (half of the bisected 60-degree angle). * - (Note that the sum of the angles does equal 180 degrees, as it must.) Now to solve for the height of a right triangle. There are a few ways. For labeling, let's let h=height of the equilateral triangle and the vertical side of the right triangle; A=every angle of the equilateral triangle (each 60o); s=side length of any side of the equilateral triangle and thus the hypotenuse of the right triangle. Since the sine of an angle of a right triangle is equal to the ratio of the opposite side divided by the hypotenuse, we can write that sin(A) = h/s. Solving for h, we get h=sin(A)/s. With trig tables you can now easily find the height.
Triangle ABC is an equilateral triangle. BC 10 What is the length of AD Give you answer to the nearest whole number?
That depends on what is meant by length of AD but the 3 sides of an equilateral triangle are all equal in lengths.

If they give you 16 63 65 is it a right triangle?
Yes because the dimensions given comply with Pythagoras' theorem for a right angle triangle
Can an isosceles triangle be a right angle triangle?
no an isosceles triangle can not be a right angle triangle because with an isosceles the two sides meet at a point creating a vertisce which a right angle triwngle does not have hope this helpsImproved Answer:-Yes it can providing the interior angles are 90 45 45 degrees which will give a triangle of two equal sides making it both an isosceles triangle and a right angle triangle.
How would you work out the perpendicular height of a triangle if they give you the area?
I think you need at least one other piece of information. A length of a side? An angle? Is it a right angled triangle?
Give an example to compute a right triangle?

Give a example of theorem on geometry?
An example is Pythagoras's Theorem: that the sum of the squares of the two shorter side lengths of a triangle with a right-angle is equal to the square of the length of the side opposite the right angle.

Can you give me an example of an area of an obtuse angle?

What is the area or the right triangle 28 cm 35 cm?
The right-angle triangle measures 28cm by 35cm. Such a triangle is half of a rectangle.Therefore 28 x 35 = 980cm2 is the area of a rectangle.980 / 2 = 490cm2 will give the area of the triangle (which is 490cm2).
Triangle ABC is an equilateral triangle What is the length of CD Give your answer to the nearest whole number?
Does length CD touch side AB at a right angle?If so, from pythagoras...(CA)sq = (CD)sq x (0.5x(AB))sqso...CD=sqrt[(CA)sq / (0.5x(AB))sq]sq = squaredsqrt = square-rootput all your known numbers in the bold equation
Can you make a rectangle out of two triangles and a square?
Sure, place a triangle's hypotenuse (longest side) on the other triangle's hypotenuse, that will give either a square or a rectangle. Then place the square on one end of the rectangle. For this to work though, the length of the square's side HAS to equal the length of the triangles hypotenuses, and likewise each triangle's hypotenuse much equal the length of a side of the square. Hope this is clear.
