draw a big triangle then make a line halfway through it
For equal sides make an Equilateral triangle. Equilateral triangles have 3 internal angles of 60o. All 3 sides are equal length. Make one using those characteristics.
Cutting the equilateral triangle in half results in two right triangles each with a base of length x/2, and angles of 30, 60, and 90 degrees. Using the lengths of sides of a 30-60-90 triangle it can be found that the height is (x/2)√(3), which is the same as the height of the equilateral triangle.So the height of the equilateral triangle is x√(3) / 2.
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
Draw a rectangle in the ratio of 1:2 eg sides of 5cm & 10cm. Bisect both the longer sides and join their mid points with a straight line. Draw a diagonal. This gives you 2 squares, 2 big triangles and 2 small triangle (1 in each square)
Ah, an equilateral triangular prism is a beautiful shape, isn't it? To find its surface area, you just need to add the areas of all its faces together. The formula is 3 times the base area (which is the area of one of the equilateral triangles) plus the lateral area (which is the perimeter of the base times the height). Just remember, there are no mistakes in math, only happy little accidents.
Construct/make a tetrahedron, which is three-dimensional.
Yes.
You have to specifically give the problem with the dots, but it can form all equilateral triangles.. .. . .. . . .
A parallelogram.
Join the 6 triangles like pizza slices
Equilateral triangles are also equiangular.
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
i have driven my friend vehicle and it slipped from the road and rolled over the ice. Do i have the right to claim to repair the vehicle.
Cross two match sticks to bisect like X and place the other two match sticks at the base of the two equilateral triangles formed .
Yes, by intersecting them.
Four
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
