A right triangle
True
isoceles
Isosceles; a triangle with two congruent (equal) sides.
No. For it to be a right angle triangle, 42 + 72 = 82. However, the left side is odd and the right side is even and so cannot be equal; thus the triangle cannot be right angled.
A right triangle
Triangle: The other shapes have an even number of sides. Square: The numbers of sides on the other two is divisible by 3 Hexagon: For sides of a fixed length, the other two shapes are rigid structures (the square can distort to a rhombus but then it is no longer a square.) or Triangle: It can have all acute angles. Square: It can (must ) have all right angles. Hexagon: It can have all obtuse angles.

They're both polygons with an odd amount of sides and verticies.
only 1 side is , which is an odd way to say that no two sides are equal.
Of course it could be even. Think of an equilateral triangle with sides of odd length.

A regular triangle, pentagon, heptagon, nonagon, etc ie Any regular polygon with an odd number of sides.
No. Equilateral triangles will tessellate and a triangle has 3 sides, which is an odd number.
