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.
Answer:
m = y1 - y2/ x1 -x2
Step-by-step explanation:
Your coordinates are (4, 1) and (0, -3) so m (slope) equals 1 - (-3) over 4 - 0 = 4/4 = 1
Hope this helped!
If you are 495 miles from home travelling at an average speed of 45 mph (miles per hour), you can find how long it will take (in hours) by simply dividing the total distance (measured in miles) by the speed (measured in miles per hour) at which you are travelling.
In simple terms, you do distance ÷ speed.
495 mi ÷ 45 mph = 11 hours.
