Wow

Yes! then there is that 3rd equal angle in there in the form of vertically opposite angles.

If 2 angles are equal, the third is automatically equal even if they weren't opposite angles.

You can also mention vertically opposite angle

Angle BCA = Angle ECD by Vertically opposite angles Since AB and ED are parallel and BD is transversal, angle ABC = angle CDE by alternate interior angles

Good stuff. I would have started with the two angles where the lines intersect, but it doesn't matter which way you go with this, because those two angles by the interesection are the same whether the outer lines are parallel or not.

Me trying to use the given values in calculations 😂😂 when the answer is so simple

Please 😢 how to find the side

Thanks ihave never been able to understand these, and now I do 😀😀

What about vertical angle theorem?

thank u

This is so easy: First, angle b is congruent to d as when a transversal crosses parallel line, alternate interior angles are congruent. angle a also congruent to e for the same reason. Angle acb congruent to dce as vertical angles are congruent. This now fulfills the angle-angle similarity criterion. Solved by 6th grader.

Thank you for the short and easy explanation shorts But if in the qn they ask the value of one side( in cm) how to solve that qn can u kindly make a short on this topic also

Bruh this is so easy

Thank you sir 😊😊😊

Thanks

Corresponding AA triangle theory

AAA postulate

nowadays you dont even need to show the angles you can just say that ab and de are parallel and by the fundamental theorem of similarity theyre similar triangles

Bro the way he drew the x 😂

The reason we write X like that is to show that it’s not times

Hi! Whats a zed angle?

When two parallel lines are cut by the transversal (tilted line up there ) then the angles made by them are equal.. Btw they are called corresponding angles.

learn alternating and vertically opposite angles too because i learned all 3 of them together but might be different for others

They have 3 sides.
