Why can all five sides figures be made from three triangles?
Because the sum of the sides of three triangles is nine... Placing three triangles together so they all touch effectively removes four of the total number of sides - leaving five.
Does all types of triangles have the same number of sides?
no they dont. the main type of triangles are isoceles equilateral and scarlene and they do not have the same numbers of sides
Are there triangles with 4 sides?
No. Triangles all have three sides.
What type of triangle has sides that are always all of different lengths?
Scalene triangles
Type of triangle that has at least two sides the same?
Isosceles triangles have 2 congruent sides. Equilateral triangles have 3 congruent sides. However, all of this works only in euclidean geometry.

Can equilateral triangles be isosceles triangles?
no. Equilateral triangles have all equal sides. Isoceles triangles only have 2 congruent sides. Isosceles triangles have 2 equal sides.
What kind of triangles have 2 sides?
None because all triangles have 3 sides
What does all the triangles look like and what type of triangle are they?
There are infinitely many types of triangles, and they can be classified according to their angles or sides (or both). Equilateral (equiangular triangles): All sides equal, all angles 60 degrees. Obtuse angled isosceles triangles: Two sides equal; one angle > 90deg. Right angled isosceles triangles: Two sides equal; angles of 90, 45, 45 degrees. Other isosceles triangle: Two sides equal; angles of 180-2x, x, x degrees. Obtuse angled scalene triangles: All sides unequal, one angle > 90 degrees. Right angled scalene triangles: All sides unequal, one angle = 90 degrees. Acute angled scalene triangles: All sides unequal, all angles < 90 degrees.
Does a triangle have 2 congruent sides?
Some, but not all. Triangles with 2 congruent sides are called isoceles triangles. Triangles with 3 congruent sides are called equilateral triangles.
Are all triangles convex?
Triangles normally have straight sides
Are all squares triangles?
No because squares have 4 sides whereas triangles have 3 sides
How many triangles in a triacontakaidigon?
A triacontakaidigon is a polyhedron with 32 sides. If the sides are all triangles, then there are 32 triangles in a triacontakaidigon, but a triacontakaidigon does not need to have triangular shaped sides.
