classification of triangles according to angles and sides

If two sides of a triangle are equal then the triangle is called an isosceless triangle. If all the three sides of a triangle are equal then the triangle is called an equilaterla triangle. If not any two of the ..

If ABC is a triangle with sides a = BC, b = CA, c = AB, then - a = b cos C + c cos B - b = c cos A + a cos C (Projection formula) - c = a cos B + b cos A ..

The sides of a right triangle that form right angle are __________. => Perpendicular or Parallel or Either A or B or None of the above..

A triangle has two congruent sides and one right angle. Classify the triangle. => isosceles right triangle or scalene triangle or equilateral triangle or None of the above..

Two corresponding sides of two triangles are congruent. The triangle, which has a larger included angle of these sides, will have ___. => larger perimeter or small area and small perimeter or smaller area or smaller perimeter..

Are the number of vertices, number of sides, and number of angles in a triangle equal? => No or Yes..

In a triangle when we refer to an angle, we mean the angle bounded by the two sides. The three angles lie in the interior region of the triangle. These angles are called the interior angles of the triangle..

Introduction - When calculating sides or angles of right angled triangles, it is easiest to use the appropriate trigonometric relation. Finding the value of trigonometric ratios from the tables is learnt easily. Nowadays of course calculators are able to give..
