It can be but need not be.
Right triange with both sides around the 90 degrees = 4 with a right trianle the area = 1/2 * height * width (think of it as half a rectangle)
A triangle has three sides and three angles. Right angled triangles are triangles in which the measure of one angle equals 90 degrees
A plane (flat) shape with three sides is called a "triangle".Notice that if it has three sides, then it must have three angles.
To find the perimeter you add and to find the area we multiply.
This is the formula to find the hypotenuse of a right angle trianle
No.
180 degrees
It can be but need not be.
Triangles are one type of polygon
Right triange with both sides around the 90 degrees = 4 with a right trianle the area = 1/2 * height * width (think of it as half a rectangle)
trianle have no faces, because it is 2D figure.
180 degrees
They are both polygons.They have a different number of sides/angles.
An equilateral triangle has 3 equal interior angles each measureing 60 degrees
Trianle Tri is Latin for three, angle is of obscure derivation.
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
