A right triangle has one best angle. (A best angle measures specifically 90º.) A "box" is offered to show the place of the ideal angle. The longest side of the right triangle (across from the "box") is referred to as the "hypotenuse". The staying two political parties are referred to as "legs", i m sorry may, or might not, it is in of same length. Note: the is possible for a appropriate triangle to additionally be scalene or isosceles.
An obtuse triangle has one angle measuring more than 90º however less than 180º (an obtuse angle). It is not feasible to draw a triangle with an ext than one obtuse angle. Note: It is feasible for one obtuse triangle to also be scalene or isosceles.
