If one angle of an isosceles triangle is 110°, what are the measures of the other angles of the triangle?
35° and 35°
In an isosceles triangle, the two base angles are equal, and all three angles sum to 180°.
Since 110° is too large to be one of two equal base angles (that would exceed 180°), it must be the unique vertex angle.
The remaining two equal angles: \(\dfrac{180-110}{2} = 35\)° each.
Hence, the other two angles measure 35° and 35°.
In a Δ ABC, if ∠A = 120° and AB = AC, then the values of ∠B and ∠C are respectively:
The product of the perimeter of a triangle, the radius of its in‐circle, and a number gives the area of the triangle. The number is
In ∆ABC, 2∠A = 3∠B = 6∠C. What is the value of the largest angle among these three angles?
The longest side in a right-angled triangle is called :
The sum of two sides of a triangle with the third side is
