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.
180 degrees
