The largested square is cut-out from a right-angled triangular region with length of 3 cm, 4 cm and 5 cm respectively in such a way that the one vertex of square lies on hypotenuse of triangle. Let us write by calculating the length of side of square.

The lengths of three sides of our triangular park are 65 m, 70 m and 75 m. Let us write by calculating the length of perpendicular drawn from opposite vertex on the longest side.

The ratio of height of the two triangles which are drawn by Suja and I is 3 : 4 and the ratio of their area is 4 : 3. Let us write by calculating what will be the ratio of two bases.

If length of each side of an equilateral triangle is doubled, what percent of area will be increased of this triangle?

If the length of each side of an equilateral triangle is trippled. What percent of area will be increased of this triangle?

The lengths of the sides containing the right angle are 12 cm and 5 cm. Let us write by calculating the length of perpendicular drawn from vertex of right angle on hypotenuse.

If each side of an equilateral triangle is 4 cm, the measure of heights is

If the area, perimeter and height of an equilateral triangle are a, s and h, then value of is

D is such a point on AC of triangle ABC so that AD : DC = 3 : 2. If the area of triangle ABC is 40 sq.cm., the area of triangle BDC is

The length of each equal side of an isosceles triangle is 5 cm. and length of base is 6 cm. The area of triangle is

Maria cycling at a speed of 18 km per hour covers along the perimeter of an equilateral triangular field in 10 minutes. Let us write by calculating the time required for Maria to go directly to the midpoint of the side of the field starting from its opposite vertex. (√3 ≅ 1.732)
