In a quadrilateral all four angles are 360 which quadrilateral u want

1Thank You

Amar Kumar 8 years, 5 months ago

A quadrilateral can be divided with a diagonal into two triangles each with an interior angle sum of 180

Explanation: If you accept that the interior angles of a triangle add up to 180

Interior angles of △ABD=p+q+r=180

Interior angles of △DBC=u+s+t=180

Interior angles of □ABCD=p+q+r+u+s+t=180+180 =360

Naveen Sharma 8 years, 5 months ago

We know
-20 = -20
16-36 = 25-45
{tex}16-36+ {81\over 4} = 25-45+{81\over 4} \\ ( 4- {9\over 2})^2= ( 5- {9\over 2})^2\\{/tex}
Taking square root both sides, we get
{tex} 4- {9\over 2} = 5 - {9\over 2}\\ 4 = 5 - {9\over 2}+ {9\over 2} \\ 4 = 5 \\ 2 + 2 = 5 {/tex}

ANSWER

Find the measure of each angle of the parallelogram , if one of its angles is 30° less than twice the smallest angle.

Posted by Parvinder Singh 8 years, 5 months ago

CBSE > Class 09 > Mathematics

1 answers

Amar Kumar 8 years, 5 months ago

let the smaller angle be x

so, other angle is 2x-30

parallelogram measures of angles are x, x, 2x-30, 2x-30

by angle sum property

x+x+2x-30+2x-30=360

6x-60=360

6x=420

x=70

so, angles are 70 ,110 ,70, 110
