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.
One star has five triangles on the sides, and about three in the middle, if enough lines are drawn.
Yes
Equilateral ( all sides are congruent), Isosceles (2 sides are congruent, Scalene (no sides are congruent), Acute ( three acute angles), Obtuse ( one obtuse angle), Right ( one right angle).
A pentagon has five sides, so two fewer sides would mean a shape with three sides. This shape is known as a triangle. Triangles are the simplest polygon and can vary in type, such as equilateral, isosceles, or scalene, depending on the lengths of their sides.
A pentagon has five sides, so a shape with two fewer sides would have three sides. This shape is called a triangle. Triangles are the simplest polygons and can come in various types, such as equilateral, isosceles, and scalene.

Because there are 540 interior degrees in a five sided figure and the total sum of three triangles is 540 degrees
It's a triangular prism - the two triangles form two ends, and the rectangles join the three sides.
seven There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles.

Yes
Pyramid. Work: 4 sides (that you usually see) are triangles, the base (bottom) is a square
A pyramid is a three-dimensional figure with five verticies and five sides (four of which are triangles and one of which is a square). A pentagon is a two-dimensional figure with five angles and five edges.
The geometric shape formed by connecting the perimeter of five points is a pentagon. Its basic construction is that of three triangles with one triangle in the middle sharing two of its sides with a base line of the other two triangles. The maximum number of triangles that can be created, if you count only those triangles that are formed by line segments between each of the five points, are ten (10).
sssThere are five methods for proving the congruence of triangles. In SSS, you prove that all three sides of two triangles are congruent to each other. In SAS, if two sides of the triangles and the angle between them are congruent, then the triangles are congruent. In ASA, if two angles of the triangles and the side between them are congruent, then the triangles are congruent. In AAS, if two angles and one of the non-included sides of two triangles are congruent, then the triangles are congruent. In HL, which only applies to right triangles, if the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent.
The shape that has 3 squares and 2 triangles is a pentagon. A pentagon is a five-sided polygon with five angles. In this case, the pentagon is made up of 3 squares, each contributing 4 sides, and 2 triangles, each contributing 3 sides. Therefore, the total number of sides in this pentagon would be 3 squares (12 sides) + 2 triangles (6 sides) = 18 sides.
