5^2 ?  3^2 + 4^
25   ?  9 + 16
25   =  25
Because the two sides are equal, this is a right triangle.

b. 5in, 6in, 7in
7^2  ?  5^2 + 6^2
49   ?  25 + 36
49   <  61

Because 49 < 61<span>, this is an acute triangle.

c. 8in, 9in, 12in
12^2  ?  8^2 + 9^2
144    ? 64 + 81
144    < 145

statuscvo [17]

Answer: Two planes meet in exactly one point

Two lines meet at exactly two points


Step-by-step explanation:

From the given statements there are two statements which are never true :-

1) Two planes meet in exactly one point .

Since when two line meets , they either meet at one point or infinite points (coincidence) , thus its impossible that they will meet at exactly two points.

2) Two lines meet at exactly two points

Since when two planes meet , the intersection of two plane always make a line not a point. Thus its impossible.
