X times Y divided by 1/2
assuming its an isosceles triangle, then its 16 cm high
The third angle of an isosceles triangle doesn't have a name.
equal
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
An isosceles triangle has three interior angles whose base angles are equal.
Area of any triangle is: 0.5*base*perpendicular height
The base angles of an isosceles triangle are congruent.
Area = 1/2*base*height = 0.825 sq cm. The fact that the triangle is isosceles is irrelevant: it makes no difference to its area.
Area of isosceles triangle: 0.5*5*7 = 17.5 square cm
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
Two sides of an isosceles triangle are equal. The base is the other side.
You can't. It is impossible.
For all triangles: area = 1/2 * base * height
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
area of a triangle is half the base times the height .5*22*28=308
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
For all triangles: area = 1/2 * base * height
