Question

The length of the sides of a triangle are 5 cm, 12 cm and 13 cm. Find the length

of perpendicular from the opposite vertex to the side measuring 13 cm.​ ​

Answer 1

Explanation:

It is clear that the triangle is a right angled triangle.

Let AB=12 cm BC=5 cm and AC=13 cm

Now a perpendicular is drawn from A to AC.

BD = AB × BC ÷ CA

Putting the respective values of the sides we get,

BD = 60 / 13 cm answer !

Answer 2

The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two.

A triangle is a 2-D polygon. A triangle has 3 sides, 3 angles, and 3 vertices. The sum of lengths of any two sides of a triangle is more than the remaining side's length. The sum of the lengths of the three sides gives the perimeter of triangles..
