Write about the sum of the measures of the angles of a triangle.

Two triangles DeltaCAB and Delta RPQ are given below. Check whether the two are congurent? If they are congruent, what can you say about the measures of the remaining elements of the triangles.

The angles of a triangle are (2x)^(@), (3x + 5)^(@) and (4x − 14)^(@) . Find the value of x and the measure of each angle of the triangle

Write about post cyclone measures?

In an isosceles triangle, the base angles are equal.The vertex angle is 40^@ .What are the base angles of the triangles? (Remember the sum of three angles of a triangle is 180^@ )

We prove the statement "sum of interior angles of a triangle is 180^@ " by

If the angles alpha, beta, gamma of a triangle satisfy the relation, sin ((alpha - beta)/(2)) + sin ((alpha - gamma )/(2)) + sin (( 3 alpha )/(2)) = 3/2, then The measure of the smallest angle of the triangle is

Given the base of the triangle and the sum of tangent of base angles as a negative constant -k^(2) , show that the locus of the vertex of the triangle is a parabola.

Equilateral triangle are drawn on the three sides of a right angled Triangle. Show that the area of the Triangle on the hypotenuse is equal to the sum of the areas of triangle on the other two sides.
