Are some right triangles are also equilateral triangles?
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
What is an isosceles and right triangles?
isosceles has 2 congruent angles 2 congruent sides right triangles has sides that consist of 2 legs and a hypotenuse. in the Pythagorean therom. a+b are legs...A2 +B2=C2 one right angle(90)
Is right triangles with 2 congruent legs is always a 454590 triangle?
Yes if you mean in degrees
Are the hypotenuses equal in two right triangles if the legs are equal?
Yes, because a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse. Therefore, if a and b are equal, so will c.
Do 2 triangles with 2 equal sides have the same area?
Only if the two triangles are congruent will they have equal areas. A third fact is required to determine they are congruent (and thus have the same area): 1) The third sides are equal; 2) The angles enclosed between the sides are equal; or 3) The same one of the sides is the hypotenuse of the triangles, which are right angled triangles.

Formula for the area of a octagon?
The interior angles of an octagon are 135 degrees, which means that if you extend one of the sides, the complementary external angle is 45 degrees. So imagine an octagon instead as a square with four cut out right triangles on the corners. Let's start with the length of a side x. Since the right triangles have a hypotenuse x, we know that the legs are length (sqrt(2)/2)x. The area of the triangle is 1/2 * base * height, which means one triangle is x2 / 4. Since there are 4 triangles, the total area of the triangles is x2. Next, we need the area of the square. One side is a leg of the octagon plus two legs of our triangles, which would be x + (sqrt(2)/2)x + (sqrt(2)/2)x = x + sqrt(2)*x. Square this, and you get 3x2 + 2*sqrt(2)*x2. But! Subtract the area of the triangles from this, and you get (after some redistributing): A = 2x2 * (1 + sqrt(2))

The legs of a right triangle are 12 and 16 inches long respectively What is the area of the triangle?
Lets work it out:- If the legs are 12 and 16 inches, then a rectangle of that size would be 192 square inches in area. As the the diagonal of the rectangle makes two equal triangles (of legs 12 and 16 inches), the area of one of these is half the area of the triangle - 192/2 = 96 square inches.
To use the HL theorem to prove two triangles are congruent the triangles must be right trianglesWhich other conditions must also be met?
1. There are two right triangles. 2. They have congruent hypotenuses. 3. They have one pair of congruent legs.
Are the hypotenuses equal in two right triangles if the legs are equal?
Yes, because a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse. Therefore, if a and b are equal, so will c.
Is the 2 legs of a triangle equal to the hypotenuse?
Not entirely. You already know that the hypotenuse is only in right triangles, and what it is, right? It's (the two legs)^2=hypotenuse^2. So, for example, if the two legs were to be 3 and 5, it would be 3^2+5^2 which would be 36. But that is the squared answer, so you have to square root it to get 6. Understand!!?
Do 2 triangles with 2 equal sides have the same area?

A third fact is required to determine they are congruent (and thus have the same area): 1) The third sides are equal; 2) The angles enclosed between the sides are equal; or 3) The same one of the sides is the hypotenuse of the triangles, which are right angled triangles.
A triangle has three sidesWhat are they?
It depends on what type of triangle you are dealing with, and also what you are meaning by what are they. If you are just talking in general terms 2 are legs, and one is the hypotenuse. In right triangles the hypotenuse is the side opposite the right angle, and the legs are adjacent to it.
Do all triangles have to have 2 acute angles?
Yes, if two of the angles in a triangle are obtuse or right, theres no logical way for the legs to meet at a point.
What is the area of a right triangle that has legs 7 cm and 4 cm long?
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.
