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)
To trisect a right angle form an equilateral triangle with one vertex at the right angle and then bisect that angle of the equilateral triangle. (It is impossible to trisect a general angle using only compass and straight edge - the right angle is a specific exception.)
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
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
Equilateral triangles are also equiangular.
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 .
Four
Yes, by intersecting them.
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°
