Its 90 degree angle is used in carpentry, cabinetry, tile work and other trades. Architect's use the triangle in their drawings.
Find out the number of matchsticks that the learners would need to build 40 triangles
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.
2 triangles and 3 rectangles
You need 3,5,7,9... triangles. They have to be equilateral triangles. 1,3,5,7... need to be upside down while 2,4,6,8... have to be right side up. ______ /\ /\ /\ / \ / \ / \ /__\/__\/__\ I know, bad picture, hopefully you get the point though.
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.
it's 3 triangles
All triangles need at least two acute angles
Triangles form other polygons as for instance there are 4 triangles in a 6 sided hexagon and 5 triangles in a 7 sided heptagon
One pentagon and five triangles.
No- triangles with all angles respectively equal need not be congruent. For example, all equilateral triangles have 3 angles of 60 degrees each but the the sides could be any length. However the sides of such triangles are proportional - such triangles are called similar. They look alike except for their scale.
