Question

Make eight identical copies of right angled
triangle of any size you prefer. For example, you
make a right-angled triangle whose hypotenuse is a
units long and the legs are of lengths b units and
c units (Fig 6.24).
Draw two identical squares on a sheet with sides
of lengths b + c.
You are to place four triangles in one square and the remaining four triangles in the
other square, as shown in the following diagram (Fig 6.25). SEE figure on page 127 of your textbook The squares are identical; the eight triangles inserted are also identical.
Hence the uncovered area of square A = Uncovered area of square B.
i.e., Area of inner square of square A= The total area of two uncovered squares in square B.
Hence a2=b2+c2. Take a=10cm,b=6cm and c=8cm

Answer 1

plzzzzzzzzzzzzzzzzz

mark me as a brainliestcovalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Answer 2

Step-by-step explanation:

To calculate the length of a side on a right-angled triangle when you know the sizes of the other two, you need to use Pythagoras' Theorem. Pythagoras' Theorem says that, in a right angled triangle: The square of the hypotenuse is equal to the sum of the squares on the other two sides.
