A parallelogram.
Join the 6 triangles like pizza slices

Equilateral triangles are also equiangular.
Make a triangle, each of whose sides is 2 matchsticks long. This uses six matchsticks. Join the middle points of the sides of this triangle to one another - using another three match sticks. You will then have four small triangles and one large one.
draw a big triangle then make a line halfway through it
Yes
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°
Using Pythagoras' theorem it is impossible for an equilateral triangle with equal sides of 10 inches to have a height of 7 inches.
