Given:
ABC is an isosceles triangle in which AC =BC.
D and E are points on BC and AC such that CE=CD.
To prove:
Triangle ACD and BCE are congruent.
Solution:
In triangle ACD and BCE,
(Given)
(Common angle)
(Given)
In triangles ACD and BCE two corresponding sides and one included angle are congruent. So, the triangles are congruent by SAS congruence postulate.
(SAS congruence postulate)
Hence proved.
Harry can first substitute 30 for t
He can then multiply by 30 to get a product of 10
Since, 10 is not equal to 15, Harry's solution is not correct.
<em><u>Solution:</u></em>
Given that,
Harry solves the equation:
He says the solution is 30
We have to check if his answer is correct or not
<em><u>Fill in the blanks to explain how Harry can check whether his solution is correct</u></em>
Harry can first substitute 30 for t
