It is a pyramid.
triangle.
Isosceles Triangle, it has 2 sides the same and 1 side different.
5 Flat surfaces 4 flat surfaces (3 for the sides and 1 for the base).
That is a "scalene" triangle.
Say you had Triangle A. Triangle A has these sides: Side 1: 9 Side 2: 6 Side 3: 6 Pretend the scale factor indicates Triangle A is 3 times the size of Triangle B, whose sides are currently unknown. To find the sides of triangle B, simply divide all the sides of triangle A by 3. You should get: Triangle B Side 1: 3 Side 2: 2 Side 3: 2 I hope that somewhat answers your question! ^-^
The answer depends on what information you do have. 3 sides, 2 sides and included angle, 1 side and any two angles, One side and perpendicular height etc. Each of these gives rise to a different formula.
a triangle with 2 sides the same and 1 side different
An isosceles triangle has two equal side; a scalene triangle has no two equal sides.
No. Each side must be shorter than the sum of the other two sides.
An isosceles triangle has two equal sides and one different side.
That is no pyramid. If it has a square side, usually the base then it will have four triangular sides
An isosceles triangle has 2 equal sides and 1 side different in length
