p: An isosceles triangle has two congruent sides = TRUE
q: A right angle measures 90° = TRUE
r: Four points are always coplanar = FALSE. 3 POINTS
s: A decagon has 12 sides = FALSE. 10 SIDES. 

p and r is a conjunction. A conjunction is true only when both statements that form it is true. p is true. r is false. Then p and r is false because not all are true.
