```“Euclidean Geometry” – UNIT V: Enrichment Unit
High School Mathematics
ESSENTIAL STANDARD
#28—Identifies and evaluates tangent, sine, and
cosine ratios for an acute angle of a right
triangle; uses a table, calculator, or computer to
find the ratio for a given angle or find the angle
for a given ratio
#29—Uses the tangent, sine, and cosine ratios
for right triangles to solve application problems
such as indirect-measurement problems
COMPACT STANDARD
#3—Uses visualization skills to explore and
interpret both two- and three- dimensional
geometric figures using such topics as
projections, cross sections, and locus problems
#48—Uses coordinate methods to explore, make
conjectures, or prove properties of geometric
figures, using tools such as algebra, graphing, and
appropriate technology
