the angle between the two sides is used in the formula A = 1/2 a*b*sin(C) where A is area, a and b are side lengths, and C is the angle between sides. Simply use algebra to rearrange the formula to solve for C.
An obtuse angled triangle.
An obtuse angled isosceles triangle.
Isosceles Triangle * * * * * In fact it is a right angled isosceles triangle.
Yes, when it has a 90 degree and two 45 degree angles it is an isosceles right angled triangle.
Because the Bottom left corner makes a 90 degree angle like this |_ and a 90 degree angle is called a Right angle thus the name Right angled Triangle
An obtuse angled triangle is wider than a right angled triangle. It has 180 degree angles.
acute * * * * * No. It is a right angled triangle.
A right(-angled) triangle
An obtuse angled triangle.
A triangle with a 90 degree angle and two 45 degree angles.
An obtuse angled isosceles triangle.
A right-angled triangle.
Yes, the definition of a right triangle is that it has a 90 degree angle
Isosceles Triangle * * * * * In fact it is a right angled isosceles triangle.
Equalateral (All sides aqual length) Isosceles (Two sides equal length, one isn't) Scalene (All sides different lengths) Right-Angled (A triangle with a 90 degree corner)
Yes, when it has a 90 degree and two 45 degree angles it is an isosceles right angled triangle.
Because the Bottom left corner makes a 90 degree angle like this |_ and a 90 degree angle is called a Right angle thus the name Right angled Triangle
