How do you find the base of a right angle triangle with the sides of 7cm and 5cm?

The answer depends on whether the base is the hypotenuse or one of the smaller legs.
If the base is the hypotenuse then its length is sqrt(7^2 + 5^2) = 8.6 cm approx.
If the base is one of the legs of the right angle, then its length is sqrt(7^2 - 5^2) = 4.9 cm, approx.

In a right triangle the sides that for the right angle are called what?
The two sides are called base and height and the sloping part of the right angle triangle is called the hypotenuse.
What is the definition for leg of a triangle?
There is no formal definition: it is any side of a triangle. Often, if the triangle has a horizontal base, then it is one of the sloped sides. In a right angled triangle, it is one of sides adjacent to the right angle. In an isosceles triangle, it is one of the equal sides.
How to measure length of two sides height diagonal of a right angle triangle where all degrees of angle and length of base given?
The answer depends on whether the base is one of the legs of the right angle or the hypotenuse. Also, a triangle cannot have a diagonal.
How do you find the area of a right angle triangle with all sides given?
(base x height) / 2
Leg of a triangle?
It is usually a side from the apex of the triangle to the base. However, in the case of a right angled triangle a leg could refer to the two sides which define the right angle.

In a right triangle the base is always longest of the 3 sides?
No. It depends what you call "base", really. The longest side is opposite the right angle.

What is the area of a right triangle that has sides measuring 10 cm15cm and 18cm?
The given dimensions would not form a right angle triangle but in general the are of a triangle is 0.5*base*perpendicular height
How do you find the area of an isosceles triangle with 2 equal sides and 1 angle?
It really depends on the angle. If the angle is at the point where the two equal sides intersect then you can divide the triangle into two equal parts (forming a right angle with the base), divide the angle by two, then use the following equation(side*arccos(your angle/2))*((side*arcsin(your angle/2)))if the angle is not where the two equal sides intersect then you can divide the triangle into two equal parts (from the point where the two equal sides intersect down to a right angle with the base) then use the following equation.(side*arcsin(your angle)*(side*arccos(your angle))
Is the base of a right triangle the largest of the three sides?
The "base" of any triangle is whatever side it happens to be sitting on in the drawing in which it's presented, and that could be any one of its three sides. In a right triangle, the longest side is the "hypotenuse", which is the side opposite the right angle. That's true whether or not the triangle happens to be drawn with the hypotenuse on the bottom.
How do you find angle in a triangle when the sides and altitude are givenin trigonometry?
Suppose you are given the three sides of a triangle and the altitude from the apex to the base. The altitude divides the triangle into two right-angled triangles and the arcsine function can be used to determine the two base angles. Subtracting their sum from 180 gives the third angle.
Can a base angle of an isosceles triangle be a right angle?
No but its apex angle can be a right angle with 2 equal base angles of 45 degrees
Why a triangle with a two 45 degrees angles is an isosceles triangle?
Because it has 2 equal base angles and 2 equal sides It is the only triangle that is both an isosceles and right angle triangle
