In triangle pq=qr=rp=7cm then find each angle of triangle pqr
if all sides are equal, so are all the angles.
Since they add to 180 degrees, each is 60 degrees.
Surely you learned this about equilateral triangles.
To find the angles of triangle PQR, we can use the fact that the sum of the angles in any triangle is always equal to 180 degrees.
Given that PQ = QR = RP = 7 cm, we can conclude that triangle PQR is an equilateral triangle because all sides are equal.
In an equilateral triangle, all three angles are equal. Let's denote the measure of each angle as x.
Since the sum of the angles in a triangle is 180 degrees, we can set up the equation:
x + x + x = 180
Simplifying the equation:
3x = 180
Dividing both sides by 3:
x = 60
Therefore, each angle of triangle PQR is 60 degrees.
