Is an equilateral triangle equal to an isosceles triangle?
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
Equilateral triangle has one angle that is exactly 90 degrees?
An equilateral triangle is a special isosceles triangle in which all three sides are congruent. Equilateral triangles are also equiangular, which means all three angles are congruent. The measure of each angle is 60 degrees.
What are the special features of a square based pyramid?
It has a four sided square base and four other triangular sides reaching up to an apex. It is a pentahedron. If the four triangles are equilateral, it is known as a Johnson solid, and six of the pyramids will fit together to make an exact cube. If the four triangles are not equilateral, then they are isosceles.
A isosceles triangle is a special type of equilateral triangle?
Not ... exactly. It would be closer to accurate to say that an equilateral triangle is a special case of the isosceles triangle.All equilateral triangles are (also) isosceles; but most isosceles triangles are not equilateral.
Why congruence is a special case of similarity?
Term similar is more wide than term congruent. For example: if you say that two triangles are congruent that automatically means that they are similar, but if you say that some two triangles are similar it doesn't have to mean that they are congruent.
Name the type of special quadrilateral that will appear when you join two congruent equilateral triangles?
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.

Can an equilaterial triangle also be an isoseles triangle?
An isosceles triangle has two congruent sides, and An equilateral triangle is a special isosceles triangle in which all three sides are congruent.Therefore, all equilateral triangles are isosceles

What are 3 types of special triangles?
iscoseles,scalene,& equilateral
What is the types of special quadrilaterals that will appear when you join two congruent equilateral triangles?
Depending on how they are joined, you can get a square, rectangle, rhombus, parallelogram, kite, arrowhead (or delta). You could also get a concave pentagon or hexagon.

What is an example of an equilateral polygon?
An equilateral polygon is one in which all sides are congruent. The angles may or may not be congruent. The simplest example is an equilateral triangle which must also be equiangular and so is a regular polygon. A rhombus is an equilateral quadrangle. The rhombus, in general, is not regular - only the square (a special type of rhombus) is regular.
Why does Wiki say that equilateral triangles are isosceles?
An equilateral triangle is a special type of isosceles triangle. It has two equal sides, which makes it isosceles; its third side is also equal, making it equilateral, too.
Name the type of special quadrilateral that will appear when you join two congruent scalene right triangles?
Two scalene right triangles that are congruent, that is, that have identical size and shape, if joined together to form a quadrilateral, will form a rectangle.
