The sum of the squares of the two smaller sides (the two sides adjoining the right angle) is equal to the square of the longest side - which is called the hypotenuse. This result is Pythagoras's Theorem.
Division by a number is the inverse operation to multiplication by the number (and vice versa).

This link gives you an excellent multiplication table and some tips.Please see related link below.
Multiplication by a positive integer can be considered as repeated addition. This can be extended to multiplication by fractions. Thus 3*4 = 4.1 + 4.1+ 4.1 (three lots of 4.1) = 12.3
It is true.
Corresponding sides of similar figures are proportional.
In gemortry, CPCTC is the abbreviation of a therom involving congrugent triangles. CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent. CPCTC states that if two or more triangles are proven congruent by: ASA, AAS, SSS, HL, or SAS, then all of their corresponding parts are congruent as well.Ifthen the following conditions are true:A related theorem is CPCFC, in which triangles is replaced with figures so that the theorem applies to any polygon or polyhedrogen.
If A times B = C and C is not 0, then the related division problems are C/A = B and C/B = A.
well, multiplication is related to additon because addition comes from multiplication because in bidmas multiplication comes first then addition that is the main term cause.
Multiplication is the inverse operation to division.
In mathematics, P.C.P.A. stands for "Principal of Corresponding Parts are Equal." This principle is often used in geometry, particularly in the context of congruent triangles, where corresponding sides and angles are equal. It helps in establishing relationships between geometric figures and proving theorems related to congruence.

DFN: we call a triangle equilateral if all sides of the triangle are the same length DFN:we call two triangles similar if corresponding angles are equal, and corresponding sides are proportional. First show that all corresponding sides are proportional: Consider a equilateral triangle with side lengths 1, all other equal lateral triangles sides can be expressed as S*(1), where S is some scalar. Hence all equilateral triangles sides are proportional to each other. Next, show that all corresponding angles are equal: The angle between two sides of a triangle is related to the length of the sides. These relationships are called sin, cos, and tan. Knowing that the cos(x), where x is one of the angles in the triangle, is the adjacent divided by the hypotenuse we see that cos(x)=(1/2)c/a, since a = c (because its equal lateral) we are left with cos(x)=(1/2) which means x = 60 degrees. this can be applied to all three angles, which shows that all three angles are 60 degrees. / \ / | \ a / | \ b /__ |__\ c We have now shown that all equal lateral triangles are similar because they all have proportional sides, and they all have equal angles.
They are both polygons.
