Select the postulate about two planes. Postulate 1: A line contains at least two points. Postulate 1a: A plane contains at least
three points not all on one line. Postulate 1b: Space contains at least four points not all on one plane. Postulate 2: Through any two different points, exactly one line exists. Postulate 3: Through any three points that are not one line, exactly one plane exists. Postulate 4: If two points lie in a plane, the line containing them lies in that plane. Postulate 5: If two planes intersect, then their intersection is a line.
Thank you for posting your question here at brainly. The two postulate planes is the below:
1: A line contains at least two points. Postulate 1a: A plane contains at least three points not all onone line. Postulate 1b: Space contains at least four points not all on one plane. Postulate
5: If two planes intersect, then their intersection is a line.
This is the concept of areas of solid figures. The surface are of the solid figure formed when 2 square pyramids are attached will be given by: SA=[number of triangular faces]*[Area of each triangle] Number of triangular faces=8 Area of each triangle=1/2*bh base=6/4=1.5 cm height=2 cm thus; Area=1/2*2*1.5=1.5 The surface area will therefore be: SA=1.5*8=12cm^2
