Because the total number of degrees in all triangle is equal to 180.
Right triangles consist of one right angle(90) and two equal acute angles(45, 45).
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
They add up to 90 degrees because there are 180 degrees in a right angle triangle
The other acute angle in that triangle is 40 degrees.
i think it would be 90 degrees and it would be a acute angle
An equilateral triangle has 3 equal interior acute angles of 60 degrees
The sume of the measures of the three nagles of an acute triangle (or any triangle) is 180 degrees.
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
The acute triangle will have 3 different acute angle that add up to 180 degrees
If each of its 3 angles are 60 degrees then it is an equilateral triangle If each of its 3 angles are different acute angles then it is a scalene triangle
An acute angle measures less than 90 degrees. While a triangle may have 2 acute angles and 1 obtuse, this is not a requirement. A triangle may have three acute angles such and a 60-60-60 equilateral triangle.
Since every type of triangle has a total of 180 degrees of angles, simply deduct the 90 of a right triangle, leaving you with a balance of ___ for the remaining acute angles.
The other acute angle in that triangle is 40 degrees.
They add up to 90 degrees because there are 180 degrees in a right angle triangle
It is: 72 degrees
There are three acute angles in an acute triangle and they add up to 180 degrees.
Any 2 angles that add up to 90 degrees because there are 180 degrees in a triangle and a right angle measures 90 degrees
No. By definition, an acute triangle is a triangle where all three angles are <90 degrees. Therefore, an equilateral triangle, where all the angles are 60 degrees would qualify as an acute triangle.
