The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
If a triangle is not scalene, then the triangle does not have three angles with distinct measures.
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 sum of the three interior angles of a triangle always total 180 degrees.
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
It is an equilateral triangle
In a triangle, the sum of the measures of the angles is 180 degrees.
If a triangle is not scalene, then the triangle does not have three angles with distinct measures.
The equilateral triangle.
a scalene triangle has no congruent sides or measures.
A right angle triangle.
It is an equilateral triangle that has 3 equal interior angles of 60 degrees
The 3 inside angles of any triangle add up to 180 degrees.
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
