How do you find the base and the height of a triangle if you have the hypotenuse?

You cannot. You need to know the length of one of the sides to find the other, or either of the acute angles.


What does an isosceles acute triangle look like?

if you know what a acute triangle looks like and you know what a isosceles triangle looks like just combined them together and then find the angles and degrees you'll find what a acute isosceles triangle looks like if you got the degrees right and angles


Can a triangle be both acute and equilateral?

It would help to know the definitions of acute and equilateral.An acute triangle is one whose angles are all less than 90o.An equilateral triangle is one whose sides are all the same, but that also means the angles will all be the same (60o)So, every equilateral triangle will be acute.Yes, a triangle can be both acute and equilateral.


Why do you know that a right triangle has no obtuse interior angles?

Because the 3 interior angles of a triangle add up to 180 degrees and if one of those angles is a right angle then the other two angles must be acute angles.


Are trigonometric functions used to find the acute angles of a right triangle?

they can be, depending on the information that you are given. If you know lengths of sides, then YES.


Are all equilateral triangle acute triangles?

An equilateral triangle has the same length for each side, and the same angle for each vertex. All triangles have a mathematical property that states that the sum of all three angles in any triangle will equal 180 degrees. Since we know that all angles are the same, and there are three of them, each angle must be 60 degrees. An acute angle is one that is less than 90 degrees, and thus, each of the three angles are acute.


How do you find the height of a triangle?

If you know the area, divide by the half the base. A = 1/2 b x hYou need to know at least one of its acute angles and then use trigonometry to find its height.The answer depends on what information about the triangle you do have.


How do you find the angles of an acute triangle?

Measure two of them. Then the third is 180 degrees minus the two that you know. Or measure the lengths of the sides and use the cosine rule.


How do you know if a triangle is acute?

A triangle is acute if it is less than 90 degrees. It is obtuse if more than 90 degrees


What are the angles that identify an obtuse triangle?

You will know that a triangle is obtuse if one of its angles is over 90°.


Is it possible for a triangle to have a 54 degree angle and a 126 degree angle?

No because the 3 angles of a triangle add up to 180 degrees and the given 2 angles already add up to 180 degrees


If one of the acute angles in a right triangle is 34o then what are the degree measures of all three angles?

Well, in any triangle, the sum of all its angles is 180 degrees. If you know that it is a right-angled triangle, then you automatically know that it has a 90 degree angle. And since it also has a 34 degree acute angle. The third angle add with 90 and 34 to equal 180.Lets call the third angle 'x'x+90+34 = 180Simplifyx+124 = 180Subtract 124 from both sidesx = 56So the third angle is 56 degrees.Therefore, your three angles are 90, 34 and 56 degrees.
