Answer:
(i) Yes
(ii) Yes
Step-by-step explanation:
We are given that 
AB=AC
(i)D is the mid-point of BC
BD=DC
In triangle ADB and triangle ADC
AD=AD
Reason: Reflexive property
BD=DC
Reason:Given
AB=AC
Reason: Given 
 ADB
ADB ADC
ADC
Reason:SSS postulate
Yes, triangle ADB is congruent to triangle ADC
(ii) Angle B=Angle C
Reason: CPCT
Yes , angle B=angle C
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'
4. Question four is then lines b and a which is option B
Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'
5. Question 5 is therefore 'a' and 'c' which is option D
 
        
             
        
        
        
Answer:
18 ft. wide by 24 ft. long
Step-by-step explanation:
this would leave a uniform strip of 2 ft around the rug and stay in her price range for 432 square feet of carpeting.
and 18 times 24 = 432 square feet
