Is 10 a right triangle?
If the length of only one side is known, it is not possible to determine whether or not the triangle is right angled.
How many altitudes can a traiangle have?
A triangle only has one altitude which is its perpendicular height.
A triangle is a right triangle if and only if it has a right angle?
True
How many right angle does a triangle?
A triangle can have only one right angle (90o). Such a triangle is called a right triangle.
If a triangle has a right angle it is a right triangle. If and only if a triangle had a right angle it is a right triangle?
A right angle triangle has a right angle and two acute angles that all add up to 180 degrees.
In a right triangle when you draw an altitude to the hypotenuse are the triangles ever similar?
Only if the angles of the triangle are 90, 45, and 45.
Is 5 a right triangle?
If the length of only one side is known, it is not possible to determine whether or not the triangle is right angled.
Is 10 a right triangle?

What is equivalence logic?
1. A triangle is a right triangle if and only if it has a right angle. 2. A triangle has a right angle if and only if it is a right triangle.
Is an altitude ever outside a triangle?
Sure. If one of the base angles is more than 90 degrees, then the altitude (height) is outside the triangle. Yes. This only occurs with an obtuse triangle. Because an altitude is a line drawn from a vertex to the opposite side and is perpendicular with that opposite side, it can only occur if it is outside the triangle. Look at the triangle in related links. If you look at the vertex on the top, the only way to draw the altitude would be to draw outside the triangle.
Can you show how a right triangle has one line of symmetry?
the only way for a right triangle to have a line of symmetry, is if the legs of the triangle are congruent. Or you can show that both non-right angles are congruent (45 degrees). you may also prove that the altitude of the triangle bisects the hypotenuse or that it equals 1/2 of the hypotenuse.
What is a logical equivalent?
1. A triangle is a right triangle if and only if it has a right angle. 2. A triangle has a right angle if and only if it is a right triangle.
What is the formula for finding the altitude of a triangle?
actually it's a2+b2=c2 the altitude is a or b and can be found by c2/a2*=b2* * a2 and b2 are interchangeable. by the way this only works with right triangles.
How do you find the length of hypotenuse when the right triangle has an altitude?
All triangles have an altitude. In fact they all have three of them. Whether or not they have an altitude, the important thing when trying to determine the length of the hypotenuse is what information you have on the lengths of the sides. Altitudes, medians can help determine the lengths of sides, as can angles. You need a minimum of 3 pieces of information. There is only one in the question: the fact that the triangle has a right angle.
How many altitudes can a traiangle have?
A triangle only has one altitude which is its perpendicular height.
