The interior angle is the set of all points in its plane, which lie on the same side

Om Tiwari 4 years, 1 month ago

examples of interior angle is angle in a triangle, angle in a rectangle angle in a square..........

Yogita Ingle 4 years, 1 month ago

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs. These angles are called alternate interior angles.

Properties

These angles are congruent.
Sum of the angles formed on the same side of the transversal which are inside the two parallel lines is always equal to 180°.
In the case of non – parallel lines, alternate interior angles don’t have any specific properties.

Parallel lines are the lines which when extended infinitely they will not meet. For example the two opposite edges of the scale aur the two opposite walls of a room While a perpendicular lines are the lines which intersect each other and makes an angle of 90°. For example the two adjacent edges of the scale or the two adjacent walls of a room.

Let the sides be 11x, 19x, 24x Perimeter = a+b+c 540 = 11x + 19x + 24x 540 = 54x 540/54 = x 10 = x 11x = 11×10= 110 19x = 19×10= 190 24x = 24×10= 240 These are the sides of triangle. Area of triangle = √s(s-a)(s-b)(s-c) (s means semi-perimeter ) s = perimeter/2 = 540/2 = 270 Area of triangle √s(s-a)(s-b)(s-c) =√270(270-110)(270-190)(270-240) = √ 270(160)(80)(30) = 10182.34

Yogita Ingle 4 years, 1 month ago

Let the ratio be 11x 19x and 24x

11x +19x+24x =540

54x =540 .: x = 540/54

Hence x=10

11x =11×10=110 19x= 19×10 =190

24x=24 × 10 =240

When the sides and angles of two triangles are equal then, they are called congruent triangle

Chanchal Sharma 4 years, 1 month ago

Two triangles are called congruent if and only if, one of them can be made to super impose on the other so as to cover it exactly and two triangles are proved congruent then their all sides and angles became exactly same by (c.p.c.t) that is corresponding parts of the congruent triangles. I hope it will help you

Yogita Ingle 4 years, 1 month ago

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles.

The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

Yogita Ingle 4 years, 1 month ago

Given, x³+y³=(x+y)(x²−xy+y²)
First take R.H.S
(x+y)(x²−xy+y²)
To multiply two polynomials, we multiply each monomial of one polynomial (with its sign) by each monomial (with its sign) of the other polynomial.
= x.x²−x²y+x.y²+y.x²−x.y²+y.y²
= x³−x²y+xy²+x²y−xy²+y³
= x³+y³
So, L.H.S = R.H.S
x3+y3=x3+y3
Hence, x3+y3=(x+y)(x2−xy+y2) is derived.
