Question

Pythagoras theorem and its converse in two and three dimensions including: chord length distance of a chord from the centre of a circle distances on a grid

Answer 1

Answer:

In a right angled triangle square of

the hypoten use is equal to the sum of the squares of the base and altitude

2) In a triangle if the sum of the squares of the Smaller sides are

equal to the square of the longer sid

e then the triangle is a right angle triangle

,3) Ifchord length is c, radius r, and the distance from th centre of the circle to the centre of the chord

then c=2vr^2-d^2

d =vr^2-(c/2) ^2

r =vd^2+(c/2)^2
