What shape has congruent angles?
Regular polygons have congruent angles such as squares and equilateral triangles.
What has 4 congruent sides but not a square?
A rhombus, diamond, lozenge or an equilateral quadrilateral all have 4 congruent sides but are not squares.
What has all sides and all angles are congruent?
Regular polygons such as squares and equilateral triangles
How many lines of symmetry does equilateral have?
If you are talking about a triangle it has two. Squares have four.
What equilateral triangles are isosceles?
No.
What shape has the same shape and same size?
A equilateral triangle and a normal triangle.
What is the problem if angles are not congruent?
None! If the angles are not congruent then the shapes are not similar of congruent. But that is not a problem. The angles of an equilateral triangle are not congruent to the angles of a square but that does not mean that you cannot work with equilateral triangles or squares!
How do you compare and contrast an equilateral triangle and a square?
Differences: Squares have 4 sides / equilateral triangles have 3 sides. Squares have 90 degree angles / equilateral triangles have 60 degree angles. Squares have 2 diagonals / equilateral triangles have none Similarities: All sides of the shape are congruent All angles of the shape are congruent
What shape has congruent angles?
Regular polygons have congruent angles such as squares and equilateral triangles.
What has 4 congruent sides but not a square?

What has all sides and all angles are congruent?
Regular polygons such as squares and equilateral triangles
How many vertices does a square triangle have?
3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.
How many lines of symmetry does equilateral have?
If you are talking about a triangle it has two. Squares have four.
What equilateral triangles are isosceles?
No.
If it is an equilateral triangle it is isosceles?
An equilateral triangle is a triangle with three equal sides. An isosceles triangle is one with two equal sides. So yes, an equilateral triangle qualifies as being an isosceles triangle as well. This is quite similar to the relationship between squares and rectangles, where a square is always a rectangle, but a rectangle isn't necessarily a square.
What types of polygons are the faces of a octahedron?
Equilateral triangles
What are angles segments triangles etc that have exactly the same measures?
They are said to be regular polygons such as equilateral triangles, squares and other polygons that have congruent sides and equal congruent interior angles.
