sin-1(a/s) where a = altitude and s = side.
Given ABE, ADC, BD bisescts angle ABC and BD is parallel to EC prove: Triangle EBC is isoceles
Assuming the lengths of the sides are given, then perimetrer = base + 2*leg If the sides are not given, then the answer will depend on what information is provided.
Isoceles triangular * * * * * Any triangle. Congruence is a relationship between two figures. Given any triangle you can always find another that it is congruent to.
It is an isosceles triangle and the 3rd angle is 72 degrees.
The dimensions given fit that of a right angle triangle
It depends on the details of the specific triangle.
No because the given dimensions do not comply with Pythagoras; theorem for a right angle triangle.
The Hypotenuse.
An equilateral triangle would fit the given description
Yes the given dimensions complies with Pythagoras' theorem for a right angle triangle.
a/o =o/a
No because the given dimensions do not comply with Pythagoras' theorem for a right angle triangle.
