Answer 1

Given Question,

To prove that,

Triangle ABD is congruent to Triangle CDB

Solution:

In triangle ABD. In triangle CDB

<BAD. = <BCD

[Since opposite angles of the given equal angles are equal]

BD. = BD

[Common side]

<ABD. = <CDB

[Since alternate interior angles of parallel sides AB and DC are equal]

Since,

All the three criteria for proving a triangle is congruent to another triangle are equal.

Hence,

Triangle ABD is congruent to Triangle CDB by ASA property.

Answer 2

Answer:

Very simply, when scientists talk about cycles, they are talking about sequences of events that repeat themselves. Some cycles are very simple. For example, the seasons of the year represent a cycle in that they always repeat Winter, Spring, Summer, Fall, and then back to Winter!
