Area of a right triangle = 1/2 base x height
Area = 1/2 10x6
Area = 30
A hypotenuse is the long side of a right triange.
that side of the triangle is only 7 inches long
The formula for the area (A) of any triangle is A = 1/2base x altitude (or height). The area of a right angled triangle with base = 8 and altitude = 28 is therefore :- A = 1/2 x 8 x 28 = 112 sq inches
Draw a line joining the top vertex to the middle of the base. This divides the triangle into two right-angled triangles, which are congruent (both have the same side lengths and angles). Each right-angled triangle has a hypotenuse length of 34 cm (the hypotenuse is the side opposite the right angle). They also have a side which is the height of the triangle, 30 cm. By Pythagoras' theorem, the third side of each right-angled triangle is 16 cm long because 342 - 302 = 1156 - 900 = 256 = 162 The base of the isosceles triangle is twice that, so it's 32 cm long.
When considering an angle in a right angled triangle, the adjacent is the short side next to the angle and the hypotenuse is the long one (which will be opposite the right angle)
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 hypotenuse is the long side of a right triange.
that side of the triangle is only 7 inches long
There is no single rule. It is a right angled isosceles triangle. Its long side (hypotenuse) is sqrt(2) times the short sides.

The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
When considering an angle in a right angled triangle, the adjacent is the short side next to the angle and the hypotenuse is the long one (which will be opposite the right angle)
Pythagoras found out that if a triangle is right-angled then the hypoteneuse (long side) squared = the other 2 sides squared and added together
294 in^2
The area is 294 square inches.
