It's important to remember that a triangle's angles will always total 180 degrees. 180 - 42 - 48 = 90. The last angle is 90 degrees, so this is a right triangle.
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 three kinds of triangles are:right triangle :one of the angles is a right angle (i.e. measures 90 degrees)acute: All of the angles measures less than 90 degrees. A special case of acute isthe equiangular or equilateral triangle in which all angles measure 60 degrees;obtuse: One of the angles measure more than 90 degrees.
A right triangle.
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
If the 3 interior angles of a triangle each measure 60 degrees then it is an equilateral triangle
The sum of the angles of any triangle is 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
The sum of the interior angles of a triangle is equal to 180 degrees.
angles that measure 90 degrees.
A triangle can't measure 75 degrees. A measure in degrees applies to angles, not to polygons such as triangles. In a triangle on a flat surface, the sum of angles is 180Â°.
That is a icocsles triangle.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
the sum ofall 3 angles of a triangle is 180 degrees. If all of them are equal, then each is 60 degrees.
The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
It is an obtuse scalene triangle.
They are all 60 degrees.
A right triangle, whose the length measure of the side opposite to the angle of 30 degrees is one half of the length measure of the hypotenuse.
An acute triangle.
Scalene or Acute triangle
The sum of the angles inside a triangle is 180 degrees.
