Answer:
1.bd=~ed given
2.CD=~fd given
3.<bdc=<edf
4.triangle BCD=~triangle def by s.s.a.axiom
5.BC=~ef the corresponding side of congruent triangle are equal
Explanation:
in triangle qrs &rst
- rs=~rs common side
- qr=~st midpoint bisect that side
- <qsr=<rst midpoint bisect that angle
4.traingle qrs =~rst by s.s.a.axiom
5.<rqs=<rts since the corresponding angle of congruent triangle are equal
Answer:
Hieroglyphs is what the ancient Egyptians and maybe some other civilization used. It is basically their writing system and their language. Hieroglyphics are based on a visualization/picture to represent and depict words. These pictures show situations or describe something.
Attached is an image/example of one. Courtesy of Google Images:
The lithospheric plates move relative to each other. They are created at mid-oceanic ridges and destroyed at subduction zones. A mid-ocean ridge is an underwater mountain system formed by plate tectonics. It consists of various mountains linked in chains, typically having a valley known as a rift running along its spine. This type of oceanic mountain ridge is characteristic of what is known as an oceanic spreading center, which is responsible for seafloor spreading. The production of new seafloor results from mantle upwelling in response to plate spreading; this isentropic upwelling solid mantle material eventually exceeds the solidus and melts. The buoyant melt rises as magma at a linear weakness in the oceanic crust, and emerge as lava, creating new crust upon cooling. A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.
Small differences between parents and offspring accumulate over time and it is called evolution. This cannot happen within a short span of time, but over a long period of time. It can also be considered as a natural selection. For the survival of the offspring due to changes in environment or any other reason can be attributed to this fact.
