What side is the hypotenuse in a right triangle?
I am guessing you mean a right angled triangle. The hypotenuse is the longest side on a right angled triangle. So it is the side facing / parallel to the right angle.
Is 7 8 12 a right triangle?
7, 8 & 12 are the sides of the triangle.And, for a right angled triangle the Pythagoras theorem is always applicable!Pythagoras theorem states that for a right angled triangle:(Longest Side)2 = (Side-1)2 + (Side-2)2(Longest side is called as the hypotenuse).So, using data in the question:If its a right angled triangle--->122 = 72 + 82i.e. 144 = 49 + 64 => 144 = 113, which is clearly not true!Hence, the triangle with the given sides is not a right triangle.
Does a right angled triangle have apex?
If you make one side the base the opposite vertex is the apex, so there are three possible apices.
How can you determine whether a triangle is a right triangle if you only know the lengths of the sides?
If it is a right angled triangle it will conform to Pythagoras' Theorm: The square of the hypotenuse = the sum of the squares on the other two sides. The hypotenuse would be the longest side, so add the two shorter sides squared together and if this equals the longest side squared then the triangle is a right angle triangle.
How do you find angles on a right triangle?
You do not need to, if you have a right triangle that angle is 90* so the other 2 angles are 45* apiece. That is actually only partially accurate. There can be a right angled triangle with sides of 2-3-5. 5 being the hypotenuse in which the triangle's angles will not be 90-45-45 but 90-33.69-56.31. To find the angles of a right triangle, you will need to know the length of the sides. With the length of all three sides, you will need to utilize sine, cosine, and tangent to find the angles.
