They are acute if every single angle is under 90 degrees, but their sum is equal to 180.

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.


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


In a right triangle one acute angle is of measure 40degree find the other acute angle please draw and show me?

Since a right triangle has 180 degree angles in it, you know 2 angles already. One is the 90 degree angle, since the triangle is a right one. The other is 40 degrees, as in your statement. 90 plus 40 is 130. 50 degrees is the missing angle since 50 + 40+ 90 equal 180 degrees. Hopefully that helped you.


How do you find the legs of a right triangle if you know the hypotenuse?

If that's all you know, then you can't. Whatever the length of the hypotenuse is, there arean infinite number of right triangles that all have the same length hypotenuse.In order to define one unique right triangle, you need to know one of the following in addition tothe length of the hypotenuse:-- the length of one leg-- the size of either acute angle


What is meant by the term love triangle?

A love triange is a relationship between three individuals. The three individuals in this relationship does not necessarily know about each person in the relationship.

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.


Which kind of angle make a triangle?

If you want to know how many degrees then I don't know but I do what kind it is acute


How do you find the base leg of a right triangle if you know the hypotenuse and one acute angle?

By using trigonometry that is applicable to a right angle triangle.


What shape has three sides that are not equal but have a right angle?

with the three sides you know it will be a triangle, it is a right triangle, it is not an equilateral triangle or an isosceles triangle... so it must be a right scalene triangle


How many angels can a triangle have?

I do not know about angels but a triangle must have exactly three angles.


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.
