Do you mean a polygon? A polygon is a two-dimensional figure.
Yes, a scalene triangle can be a triangle.
a triangle in a triangle
A triangle is the same as a equilateral triangle because a equilateral triangle is a triangle but it is congruent on all sides
there is equilateral triangle, right triangle, isosceles triangle, obtuse triangle, acute triangle, scalene triangle and oblique triangle
A pentagon
dodecagon
it is called a nonagon
Do you mean a polygon? A polygon is a two-dimensional figure.
7?
Yes an octagon is an 8 sided polygon
An isosceles trapezoid would fit the given description
A regular n-gon is a polyon that has n sides of equal length, and thus n angles of equal degree (see related link for what this degree would be).
any triangle is a triangle
If a triangle is obtuse, the orthocenter of the triangle actually lies outside of the triangle. If the triangle is acute, the orthocenter of the triangle lies on the inside of the triangle
Triangles can be classified based on their sides and angles. Based on sides, triangles can be equilateral (all sides are equal), isosceles (two sides are equal), or scalene (no sides are equal). Based on angles, triangles can be acute (all angles are less than 90 degrees), obtuse (one angle is greater than 90 degrees), or right (one angle is exactly 90 degrees).
