Question

please help me to solve and give the right answer
(ch-name:-special types of quadrilateral)​

Answer 1

Answer:

I give one hint to you

Step-by-step explanation:

first you write the given things

then and use the property

Answer 2

Step-by-step explanation:

GIVEN; ABCD IS PARALLELOGRAM IF FOLLOWING CONDITIONS ARE RIGHT.

2. ANGLE A = 95 , ANGLE B = 75

AS WE KNOW ,AC II BD ( OPPOSITE LINES ARE II IN II GM )

THEN ,A + B = 180 ( SUM OF INTERIOR ANGLES )

95 + 75 = 170 IS NOT EQUALS TO 180

SO ,THIS CONDITION CANNOT FORM ABCD AS A II GM

3. ANGLE B = 105 ,ANGLE D = 75

AS WE KNOW ( OPPOSITE LINES ARE II IN II GM )

THEN , AB II CD

ANGLE B + ANGLE D = 180 ( SUM OF INTERIOR ANGLES )

105 + 75 = 180

SO CONDITION (3) CAN FORM ABCD AS II GM.

1. AB = CD = 5CM , AD = 3.8 CM , BC = 3.6 CM

STEP A. USE THE GIVEN TO PROVE TRIANGLE ABO IS CONGRUENT TO TRIANGLE COD

STEP B. THEN PROVE ANGLE ABC = ANGLE BCD, AS ALTERNATE INTERIOR ANGLES

STEP C. THEN ,BY CONVERSE OF A.I.A. THEOREM , AB II CD .

STEP D. SO IF IN A QUADRILATERAL ,A PAIR OF SIDES ARE PARALLEL AND EQUAL THEN THE ABCD IS A II GM.
