Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH). When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat.
Question:If the measure of angle G equals 35 and the measure of angle S equals 35, then the measure of angle G is congruent to the measure of angle S (the last part doesn't make sense to me to use congruent because you're dealing with measures, but it's what the problem is telling me).
