Answer:
For statement 2, reason is Segment addition postulate.
Statement 3 and reason is
BD=AC+CD using substitution property of equality.
Statement 4 and reason is
AC+CD=BD using symmetric property of equality
Statement 5 is
BD= BC+CD
Statement 6 and reason is
AC+CD=BC+CD using transitive property of equality
Reason for 7 is
Subtraction property of equality.
Step-by-step explanation:
For statement 2, we use segment addition postulate to say AC= AE+EC.
Answer:
Step-by-step explanation:
<u>Using Pythagorean Theorem first to find EC</u>
<u>Given that:</u>
AE = EC
AE = 12 cm
Now,
AB = AE + EB
AB = 12 + 5
AB = 17 cm
<u>ABCD is a trapezoid / trapezium</u>
So,
Area of Trapezium =
Where AB = 17 , DC = 8 and EC = 12
Area of Trapezium =
Area of Trapezium = (25)(6)
Area of Trapezium = 150 cm²
