How many triangles can you find in a square?
no triangles
How do you find out the angles of of equilateral triangles?
Any equilateral triangle has 3 sides of equal lengths and 3 equal interior angles of 60 degrees. 3*60 = 180 degrees.
How do you find an area of a RHOMBOID?
Find the area of the square and two triangles that compose the rhomboid.
How do you find the diagonals of a square when you have the area of the square?
A diagonal bisecting a square creates two identical right triangles. The diagonal is the hypotenuse of a right triangles, so its length is the square root of the sums of the squares on the opposite two sides.
If each side of the equilateral triangle measures 9c find the height of the triangle?
The area of a triangle is one-half the product of the triangle's base and height. The height of an equilateral triangle is the distance from one vertex along the perpendicular bisector line of the opposite side. This line divides the equilateral triangle into two right triangles, each with a hypotenuse of 9c and a base of (9/2)c. From the Pythagorean theorem, the height must be the square root of {(9c)2 - [(9/2)c]}, and this height is the same as that of the equilateral triangle.
How many triangles can you find in a square?
no triangles
How do you find surface area of an equilateral triangles?
Area = 0.5*base*perpendicular height
What is the height of an equilateral triangle with the side lengths of 18 center meters?
In effect an equilateral triangle is made up of two right angle triangles joined together so use Pythagoras' theorem to find the height:- 182-92 = 243 and the square root of this will be the height of the equilateral triangle which is about 15.588 cm
If a triangle is equilateral then it is isosceles What is the converse of the statement?
If a triangle is isosceles, then it is equilateral. To find the converse of a conditional, you switch the antecedent ("If ____ ...") and consequent ("... then ____."). (Of course, if not ALL isosceles triangles were equilateral, then the converse would be false.)
How do you find the area of a square inside a circle with the radius of 24cm?
Easy way to work it out: Break the square down into four equilateral triangles, formed by the border of the square and two diagonal lines intersecting it. Each of those triangles will be right isosceles triangles, with their sides adjacent to the right angle each having a length that is equal to the radius of the circle. Their area then would be the square of that radius, divided by two (a = wh/2). Each of those four triangles then, has an area of 242 / 2. There are four of those triangles forming the square, so it's area would be 2 * (24cm)2, or 1152 cm2.
How do you find out the angles of of equilateral triangles?
Any equilateral triangle has 3 sides of equal lengths and 3 equal interior angles of 60 degrees. 3*60 = 180 degrees.
A net that has 4 triangles?
the answer is pyramid
What faces would you find in a net for a square pyramid?
4 triangles and 1 square.
How do you find an area of a RHOMBOID?
Find the area of the square and two triangles that compose the rhomboid.
How do you find aras of triangles and parallelograms?
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
How do you find the diagonals of a square when you have the area of the square?
A diagonal bisecting a square creates two identical right triangles. The diagonal is the hypotenuse of a right triangles, so its length is the square root of the sums of the squares on the opposite two sides.
What is the perimeter of an equilateral triangle with an altitude of 15?
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
