In the following figure, determine the intersection of plane π΄π·π΄ prime and plane π΅π·π΅ prime.
00:00:13.030 --> 00:00:16.820
First, letβs identify plane π΄π·π΄ prime.
00:00:17.300 --> 00:00:27.310
π΄π·π΄ prime, we know that a plane is a flat two-dimensional surface that extends infinitely.
00:00:28.380 --> 00:00:35.020
And that means that plane π΄π·π΄ prime does not just include this triangular piece.
00:00:36.130 --> 00:00:42.330
It includes these spaces and continues to extend in all directions.
00:00:43.180 --> 00:00:48.990
Letβs go ahead and identify the plane space that includes π΅π·π΅ prime.
00:00:49.420 --> 00:00:57.450
π΅π·π΅ prime, here is the shape created by π΅π·π΅ prime.
00:00:58.700 --> 00:01:04.030
And here is a representation of the plane that π΅π·π΅ prime lies in.
00:01:05.350 --> 00:01:08.360
Hereβs a reduced sketch of these two planes.
00:01:09.780 --> 00:01:14.230
We remember that the intersection of two planes is a line.
00:01:15.260 --> 00:01:20.610
We need to identify the line that is the intersection of these two planes.
00:01:22.270 --> 00:01:27.760
Line πΆπΆ prime is the intersection of these two planes.
00:01:28.990 --> 00:01:41.330
What we mean by that is at every point along the line πΆπΆ prime is both plane π΄π·π΄ prime and plane π΅π·π΅ prime.
