Are triangles equilateral?
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
What shape has three different sized sides?
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.
Are there triangles with 4 sides?
No. Triangles all have three sides.
What can you make with 3 triangles?
we can make a trapezium with 3 equal triangles.
Does a triangle have any lines of symetry?
Scalene triangles have none. Isosceles triangles have one, and equilateral triangles have three.
What three shapes can be put together to make a trapezoid?
Three triangles.

No. Triangles all have three sides.
What shapes can you make out of three triangles?
You can make any triangle, quadrilateral or pentagon with three suitable triangles.
What is three types of triangles?
They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles
What can you make with 3 triangles?
we can make a trapezium with 3 equal triangles.
How A pentagon can be divided into how many triangles by drawing all of the diagonals from 1 vertex?
Three triangles
Does a triangle have any lines of symetry?
Scalene triangles have none. Isosceles triangles have one, and equilateral triangles have three.
Are triangles similar?
there are three different triangles. the iscocelese, equalateral and right. so no
What are facts about triangles?
They have three sides and three angles
How you can prove that the angles of two triangles are equal?
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
