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.)
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
A right triangle.
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 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 180°.
The sum of the angles of any triangle is 180 degrees.
90 degrees
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.
