A right triangle. * * * * * Not necessarily. All that can be said is that is is not an equilateral triangle. It can be isosceles or scalene. It can be acute angled, right angled or obtuse angled.
A right-angled triangular prism is called a right prism. The formula for calculating the volume of a prism is V = B x h, where B = area of base, and h = height of the prism.The area for the base is calculated using the formula B = 1/2(length x height) (area of a triangle).Example: The height of a prism is 10 cm. The base is a right triangle with legs of length 5 cm and 12 cm, soB = 1/2(5x12)B = 30cm2V = B x h = 30cm2 x 10cmV = 300cm3
