The area of a triangle ABC whose base is of 12 inches and a height of 3 inches is:A18 inches2B30 inches2C36 inches2D40 inches2Please answer this question

Answer»

Question :- The area of a triangle ABC WHOSE base is of 12 inches and a height of 3 inches is :

A)18 inches2

B) 30 inches2

C) 36 inches2

D) 40 inches2

Solution :-

Triangle :--- is a plane figure with three straight sides and three angles.

→ Area of ∆ = 1/2 * Base * Height = 1/2* ab* sinC = 1/2 * bc *sinA = 1/2 * CA* sinB = √( s(s-a)(s-b)(s-c) ) [ where s = (a+b+c)/2 ]

given that,

Base = 12 inches .
Height = 3 inches .

then,

→ Area of ∆ABC = (1/2) * Base * Height

→ Area of ∆ABC = (1/2) * 12 * 3

→ Area of ∆ABC = 6 * 3

→ Area of ∆ABC = 18 inches² . (A) (Ans.)

Square ABCD is congruent to Square EFGH. If the perimeter of square ABCD = 40cm , find the area of square EFGH ,a]100 sq.cmb]10 sq.cmc]200 sq.cmd]25 sq.cm

Answer»

ANSWER:

perimeter of square ABCD = 4 X s

40 cm = 4 x s

s = 40/4 = 10cm

as both the squares are congruent or EQUAL,

measures of the side of square EFGH = 10cm

area of square EFGH = s x s

= 10 X 10 = 100 cm²

therefore the answer is a) 100 sq.cm

8.	Prove mid point theorem
Answer» Answer: If the line segment adjoins midpoints of any of the sides of a triangle, then the line segment is said to be parallel to all the remaining sides, and it measures about half of the remaining sides. Consider the triangle ABC, as shown in the above figure, Let E and D be the midpoints of the sides AC and AB. Then the line DE is said to be parallel to the side BC, whereas the side DE is half of the side BC; i.e. DE∥BC DE = (1/2 * BC). Now consider the below figure, the figure is in the picture. Construction- Extend the line segment DE and produce it to F such that, EF = DE. In triangle ADE and CFE, EC = AE —– (given) ∠CEF = ∠AED (vertically opposite angles) EF = DE (by construction) By SAS congruence criterion, △ CFE ≅ △ ADE Therefore, ∠CFE = ∠ADE {by c.p.c.t.} ∠FCE= ∠DAE {by c.p.c.t.} and CF = AD {by c.p.c.t.} ∠CFE and ∠ADE are the alternate interior angles. Assume CF and AB as two lines which are intersected by the transversal DF. In a SIMILAR way, ∠FCE and ∠DAE are the alternate interior angles. Assume CF and AB are the two lines which are intersected by the transversal AC. Therefore, CF ∥ AB So, CF ∥ BD and CF = BD {since BD = AD, it is proved that CF = AD} Thus, BDFC forms a parallelogram. By the properties of a parallelogram, we can write BC ∥ DF and BC = DF BC ∥ DE and DE = (1/2 * BC). Hence, the midpoint theorem is proved.

Prove mid point theorem

Answer»

Answer:

If the line segment adjoins midpoints of any of the sides of a triangle, then the line segment is said to be parallel to all the remaining sides, and it measures about half of the remaining sides.

Consider the triangle ABC, as shown in the above figure,

Let E and D be the midpoints of the sides AC and AB. Then the line DE is said to be parallel to the side BC, whereas the side DE is half of the side BC; i.e.

DE∥BC

DE = (1/2 * BC).

Now consider the below figure,

the figure is in the picture.

Construction- Extend the line segment DE and produce it to F such that, EF = DE.

In triangle ADE and CFE,

EC = AE —– (given)

∠CEF = ∠AED (vertically opposite angles)

EF = DE (by construction)

By SAS congruence criterion,

△ CFE ≅ △ ADE

Therefore,

∠CFE = ∠ADE {by c.p.c.t.}

∠FCE= ∠DAE {by c.p.c.t.}

and CF = AD {by c.p.c.t.}

∠CFE and ∠ADE are the alternate interior angles.

Assume CF and AB as two lines which are intersected by the transversal DF.

In a SIMILAR way, ∠FCE and ∠DAE are the alternate interior angles.

Assume CF and AB are the two lines which are intersected by the transversal AC.

Therefore, CF ∥ AB

So, CF ∥ BD

and CF = BD {since BD = AD, it is proved that CF = AD}

Thus, BDFC forms a parallelogram.

By the properties of a parallelogram, we can write

BC ∥ DF

and BC = DF

BC ∥ DE

and DE = (1/2 * BC).

Hence, the midpoint theorem is proved.
