The Pythagorean Theorem is a statement about triangles containing a right angle. The Pythagorean Theorem states that: "The area of the square built upon the hypotenuse of a right triangle is equal to the sum of the areas of the squares upon the remaining sides." Bhaskara's Proof of the Pythagorean Theorem In this proof, Bhaskara began with a right triangle and then he drew an altitude on the hypotenuse. From here, he used the properties of similarity to prove the theorem. Now prove that triangles ABC and CBE are similar. It follows from the AA postulate that triangle ABC is similar to triangle CBE, since angle B is congruent to angle B and angle C is congruent to angle E. Thus, since internal ratios are equal s/a=a/c. Multiplying both sides by ac we get sc=a^2. Now show that triangles ABC and ACE are similar. As before, it follows from the AA postulate that these two triangles are similar. Angle A is congruent to angle A and angle C is congruent to angle E. Thus, r/b=b/c. Multiplying both sides by bc we get rc=b^2. Now when we add the two results we get sc + rc = a^2 + b^2. c(s+r) = a^2 + b^2 c^2 = a^2 + b^2, concluding the proof of the Pythagorean Theorem.

Ice is less density than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

Heena Kathuria | 1 day ago

Because volume of ice is more than water.

According to Mathematician Pythagoras "The Sum of the Squares of the Altitude and the Base of any Right angled triangle must be equal to the Square of the Hypotenuse."Thus we can say that if ABC is a right angled triangle at B then AC^2 =(AB^2)+(BC^2). sometimes also written as h^2 = b^2 + p^2.
