## Geometry

Polygon: Two types of angle

1. Exterior
2. Interior
1. Exterior Angle: Sum of exterior Angle of the polygon is 360°, Interior Angle: Sum of the interior angle of the polygon is (n – 2)× 180. 1. Vertical opposite angle always be same -: ∠ 1 = ∠ 3  and ∠ 1 + ∠ 2= 180°

-: ∠ 2 = ∠ 4  and   ∠ 3 + ∠ 4 = 180°

1. Corresponding angles:

∠ 4 + ∠ 5 = 180°

∠ 3 + ∠ 6 = 180° 1. Sum of 2 interior angle opposite to exterior angle 5. In the given fig. AB = AC, then AD which is median of the triangle also be height of triangle • In the given fig. ABCD is a cyclic quadrilateral. ∠ A + ∠ C = 180°  (opp. Angle)

∠ B + ∠ D = 180°

⟹ opposite interior angle is equal to exterior angle.

• Centres of the triangle:

Type of centres:

• Centroid
• Incentre
• Circum-centre
• Ortho – centre

(1) Centroid: Intersecting points of the medians of triangle is known as centroid of the triangle. Area of ∆ ABD = ∆ ACD

AG : GD = 2 : 1

Area of ∆ BGC = ∆ AGC = ∆ AGB

Area of ∆ nzGY : ∆ ABC

2 : 36

1 : 18

Example: PS is the median of a triangle PQR and O is centroid such that PS = 27 cm. The length of PO is

Sol. PS is the median and O is the centroid —– (given)

PS = 27 cm

Ratio of PO : OS

(2) Incentre:  Intersecting points of angle bisector of triangle is known as Incentre of the triangle Ix = Iy = Iz = radius Example: O is the incentre of triangle PQR, ∠ PQR = 70° and ∠PRQ = 60°, Then find the value of ∠ QOR.

Sol. Acc. to Question QO and RO are the angle bisector

∴ ∠ RQO = 35° and ∠ QRO = 30°

In ∆ QOR, ∠ RQO + ∠ QRO + ∠ QOR = 180°

35° + 30° + ∠ QOR = 180°

∠ QOR = 180° – 65° ⟹ 115°

(3) Circum-centre: Intersecting point of the perpendicular bisector of triangle is known as circum-centre of the triangle AO = OB = OC = Radius

∠BOC = 2 (∠BAC)

In right ∠ ∆ circum-centre is formed on the mid-point of hypotenuse.  (4) Ortho-centre: intersecting points of the altitudes of triangle is known as orthocentre of the triangle Example:  In an obtuse angled triangle ABC, ∠B is obtuse angled and O is orthocentre. ∠ AOC = 69° and ∠ ABC is

Sol. ∠ ABC = 180° – ∠ AOC

= 180° – 69°

= 111°

Some important facts of the triangle:

1. Mid-Point Theorem: In triangle ABC, P and Q are mid – point of AB and AC. Then PQ always || to BC (PQ || BC). 1. Median theorem: In ∆ ABC, AD is Median Example: If the length of the three sides of a triangle is a 9 cm, 40 cm, and 41 cm then find the length of median to its greatest side.

Sol. This is a right-angled triangle • Angle bisector theorem: Internal angle bisector External angle bisector: • In the right Triangle ABC, F and D is the mid – points of AB and BC Practice More Mathematics  Quiz Here

## Simple Interest

Simple interest is nothing but the fixed percentage of the principal (invested/borrowed/ amount of money).

Principal (P): It is the sum of money deposited/ loaned etc. also known as “Capital”.

Interest: It is the money paid by the borrower, calculated on the basis of Principal.

Time (T/n): This is the duration for which money is borrowed.

Rate of Interest (r/R): It is the rate at which the interest is charged on principal.

Amount (A) = Principal + Interest

Some Basic Formulae :

Simple Interest (SI): P = Principal,

r = rate of interest (in %)

t = time period (yearly, half yearly etc.) Some Useful Short-cut Methods:

1. If a certain sum in T years at R % per annum amounts to Rs. A, then the sum will be 1. If a certain sum is invested in n types of investments in such a manner that equal amount is obtained on each investment where interest rates are R₁R₂ R₃ …..Rn respectively and time periods are T₁ T₂ T₃….. Tn respectively, then the ratio in which the amounts are invested is : 1. If a certain sum of money becomes n times itself in T years at simple interest, then the rate of interest per annum is 1. If a certain sum of money becomes n times itself in T years at a simple interest, then the time T in which it will become m times itself is given by 1. Effect of change of P, R and T on simple interest is given by the following formulae:

Change in Simple Interest For example, if rate (R) changes from R₁ to R₂ an P and T are fixed, then Similarly, if principal (P) changes from P₁ to P₂ and R and T are fixed, then change in Also, if rate (R) changes from R₁ to R₂ and time (T) changes from T₁ to T₂ but principal (P) is fixed, then change in 1. If a certain sum of money P lent out at S.I. amounts to A₁ in T₁ years and to A₂ in T₂ years, then # Important Mathematics Questions for MPTET 2020 : 29th January 2020
