I'm not sure if you're missing a "NOT" in the question, or the wording is wrong, but three of these are theorems or postulates used to prove triangles congruent, while one is not.
Angle-side-angle (ASA) is used when two angles and an included side are congruent, side-side-side (SSS) is used when all three sides are congruent, and side-angle-side (SAS) is used when two sides and an included angle are congruent. All these are theorems or postulates used to prove triangles congruent.
Angle-angle-angle (AAA), however, is not.
I hope this helps you.
Answer:
Explanation:
Ecology: It is the discipline of biology. It studies the interaction between the organisms and their interaction with their non-living physical environment. It suggests that what factors influence the distribution and abundance of organisms.
Ecosystem: It is a biotic community in which living beings interact with their non-living physical environment. In other words the ecosystem is a place where living beings (biotic factors) interact with the non-living beings (abiotic factor).
Organism: An organism is an individual which belongs to a particular species or life form. An organism perform functions necessary to survive. It exhibit features of living being. The example of organism includes the plants, animals, fungi, and others.
Population: It is a group of members of the same species which are capable of reproducing and producing viable fertile offsprings. The population may vary in functional and morphological forms.
Community: A community is a group of two or more distinct species. These species interact among themselves so as to survive and performing functional roles in the ecosystem. For example, plants provide food to animals in return the animals disperse the seeds of the animals.

Answer:
Correct answer is:
A. Canadian Shield
B. Coastal Range
C. Intermountain region
Explanation:
North America is usually divided into eight regions.
As we can see from map Canadian Shield is the largest region, that covers larger part of Canada.
As we can see coastal range is covering territory along the Pacific, while Intermountain region is going along the coastal range.
